Toolik Field Station is located at mile 284.5 of the Dalton Highway, 370 miles north of Fairbanks. 

Driving to the station takes 9-12 hours over a largely unpaved industrial artery that serves operations at Prudhoe Bay.

There is no cell reception anywhere on the Dalton Highway, so having a satellite phone or an InReach GPS tracker is recommended. CB radios are commonly used by truckers to communicate hazards and other safety information, and are also recommended for any vehicles that traverse the highway.

There are little to no options for supplies along the way, so food and drinks should be planned out and brought beforehand.

The majority of our visitors travel to and from Toolik Field Station via a fleet of NSF-owned and Toolik-managed Science Support vehicles on a set schedule, but there are other options available to reach the station. Visit our Transportation page for details.

Toolik Field Station operates year round, with summer operations differing greatly from winter operations.

"Summer" season: May-September

Toolik Field Station is fully operational and staffed with maintenance technicians, cooks, operations staff, a safety coordinator and EMT,  Environmental Data Center and GIS experts, a naturalist, and access to 100% of the buildings at the station. 

During the summer season the user day rate will cover your housing, food, field assistance, transportation, equipment, lab or other building access, and any other type of support that might be needed while doing work at Toolik Field Station. The kitchen is fully staffed and provides hot meals 2-3 times a day (except on Sunday), as well as 24/7 self-served food as needed

"Winter" season: October-April

Only "essential buildings" remain open and heated: Dining Hall, Garage, Cottongrass dorm, Winter lab, Winter Quarters, generator modules, and the well house. The station is minimally staffed with at least 4 personnel to maintain continuous heat, power, and water utilities, and to provide remote access and other support as needed

During the winter months Toolik Field Station is still open to visitors but operates with reduced services. Only a hot dinner is served, with self-serving options for other meals. Lab space is limited to the winter lab, and is shared between all projects doing work at Toolik. Accommodations are in one of our winter capable hard-sided dorms. Support requests (field assistance, equipment use, etc.) need to be coordinated with Toolik staff ahead of time.

Science project members are responsible for providing their own field clothing and gear. During the summer months weather is difficult to predict and can turn quickly. We recommend that you bring cold weather clothing in addition to summer clothing to be prepared for any weather. Fabrics to consider are Polar Fleece, polypropylene, Capilene, wool, and silk. Avoid cotton fabrics and jeans for remote field site use. Rain is frequent in the summer, so good rain gear is a must! Don't forget to plan for warm weather as well, as we can see temperatures in the 80s!

If applicable, please make sure to indicate your dietary limitations when you complete your profile in the myToolik system. The kitchen will attempt to accommodate requests, but it may not be possible to prepare separate options to meet requests for every meal.

We ask staff and users to stick to the meal plan that they sign up for at the beginning of the season to help facilitate planning meals.

There are a few basic diets at Toolik:

  1. Regular - (Fish/Meat available at each meal)
  2. Pescatarian - Fish 2-3 times a week, Vegetarian the rest of the time.
  3. Vegetarian
  4. Vegan

The regular hot meals are scheduled at 7:30-8:30 for breakfast, 12:00-13:00 for lunch, and dinner is at 18:00-19:00. Outside of those hours, self-served food is available in the dining hall refrigerator chillers. We also provide a variety of bags and wrappers to take food with you into the field. 

Self-served food include: left-over food, sandwich and salad bar, snacks, soft drinks, a wide variety of milks (both dairy and non-dairy), Gatorade powder, coffee, and teas. Self-served food is available 24/7 in the Dining Hall.

Arctic Bread

We may be located in the Arctic but we have access to a variety of communication services. 

  • Internet access:
    • Toolik Field Station is operated by the University of Alaska Fairbanks and all internet services are provided through their Office of Information Technology (OIT). While outages are rare they do happen, but service is typically restored in a timely manner.
    • Wireless internet is reliably available throughout most the station. There are a few dead spots, but you should have access to the Wi-Fi in most buildings around the station.
    • Hardwired Ethernet capabilities are available and especially helpful when working inside laboratories
    • Illegal downloads are prohibited, and will be monitored and tracked by OIT. Multiple offense computers will be banned from the network
    • All computers must have up-to-date antivirus software.
    • While the station has fairly fast internet, please keep in mind that it is shared with many others. It is important that everyone keeps their downloads and streaming to a minimum
  • Phones:
    • Toolik Field Station has a variety of public phones around the station that everyone is welcome to use. The station map has a directory of all of the station phone numbers. These phones only dial within the state of Alaska (907 area codes). They are linked to the UAF campus, so if you know the 4-digit extension of the number you try to call on campus you can dial directly
      • Station Manager: x2511
      • EMT: x2516
      • Maintenance: x2523
      • Updated phone lists are posted throughout the station. 
      • For other numbers, dial 8, then 1 and the number with 907 area code. 
      • Talk to the staff if you need to make a long distance call. 
  • Cell phones:
    • There is no provider that works at Toolik and you won't have reception anywhere close to the station. Since 2019, there has been an increase cell service coverage along the Dalton Highway.
      • The two main cell phone service providers on the North Slope are GCI and AT&T, please visit their websites for coverage maps. Additionally, here is a FCC mobile coverage map that shows some additional services that are not yet shown on the GCI or AT&T coverage maps.
      • Service is frequently found with AT&T and GCI near the pump stations and DOT stations along the haul road.
    • There is a work around to use your cell phone while at the station via Wi-Fi! If your provider allows Wi-Fi Calling, make sure to enable the service (free in most cases, check with your provider) before you lose reception on the Dalton. You won't be able to enable the service once at Toolik so make sure to activate it while still in Fairbanks! Once enabled, you will be able to make calls, receive/send text messages, etc. while on Wi-FI as if you were within cell reception
  • Satellite phones:
    • Toolik has a stock of satellite phones available to check out each day to take into the field. 
    • All Toolik fleet trucks are equipped with a satellite phone in case of an emergency, and the Science trucks shuttling between Fairbanks and Toolik also are equipped with an InReach that track the location of the vehicles. 
  • Radios:
    • Toolik staff carry hand-held radios at all times. There is a base station radio in the staff office that anyone is welcome to use if they are trying to reach a staff member. 
  • inReach:
    • Toolik has a small supply of inReaches that are available for check out.

Water conservation is a high priority at the station. TFS has no water treatment facility, thus all sewage and wastewater must be stored and trucked to Prudhoe Bay for treatment at great expense. For this reason, we limit showers and laundry to a minimum.

In 2022 the Washeteria opened at Toolik Field Station to provide an updated washing facility on the residential portion of the field station. The Washeteria is ADA compliant with ramps and a ADA compliant shower stall. 


The primary bathrooms at Toolik Field Station are outhouses which are known as "towers". They are towers since they are elevated and have stairs to them. Their are five towers situated throughout the field station. Additionally, there are four flush toilets at the field station. Please, use the towers over the flushable toilets in order to conserve water.

Please do not throw anything in the toilets or down a tower. All wastepaper goes into a trash can adjacent to the toilet.

All of the towers and bathrooms are stocked with toilet paper, wipes, and menstruation products. Please bring your own menstruation products for your stay, however, we got you in case of an emergency.


In the summer months, showers at the station are located in the Washeteria, located on the residential side of the station. The Washeteria is co-ed with 7 individual lockable stalls. All TFS residents should limit their bathing to 2 short (~2min) showers per week. There are water-saving “pause” valves on all shower heads. There are two additional showers in Cottongrass, these are the only operational showers in the winter months.

In the central portion of the Washeteria there is a room full of sinks and mirrors for brushing teeth and getting ready. Additionally, there are cubbies located in the Washeteria for storage of your toiletries. Please label your cubby with your name and departure date.


Residents may do one load of laundry every two weeks. The washing machines at Toolik are high-capacity and high-efficiency. The station provides high-efficiency (HE) laundry detergent. Please make sure loads are full to make the most of a load. Consider combining clothes with another resident in needed.


The sauna is a welcoming environment, if you have never sauna'd ask someone for advice so you can enjoy it too. If you are about to take your first sauna or are sauna connoisseur please review the Toolik Sanua Rules.

The TFS has played a key part of our water conservation efforts. The sauna was re-built during the winter of 2019/2020. The sauna operates several times a week during the summer months and on request during the winter months.

Sauna Hours (summer):

  • Monday, Wednesday, Friday, and Sunday
    • Men: 6-7:30 pm
    • Women: 7:30-9 pm
    • Open: 9pm on wards
    • Transgender/Genderqueer/Non-Conforming hours on Sunday 4:30-6 pm

Always observe your gender's designated hours

  • Non-Binary, Trans, Two Spirit, & gender non-conforming residents can use whichever hours they feel most comfortable attending. 

There are two rooms to the sauna: changing room and the heated sauna. The first is exterior changing room where there are cubbies for your belongings while you sauna and hooks for towels. You may want to bring your own towel, however, as there is a limited supply of towels that are available on a first come first served basis. The sauna is clothing optional, please respect peoples decision on how they would like to bathe. The second room is the sauna itself. The sauna is heated by a wood-fired stove, typically the sauna is around 175-230 °F. Additionally, there are two rows of benches for sitting on while saunaing. 

There are pitchers of water along a banister which surrounds the wood-fired stove in the sauna, caution the pitchers and the water get very hot while the sauna is running and you will need an oven mitt to move them. Cold water is pumped up to the sauna deck to customize the temperature of the pitcher water before using it to bathe. Bathing occurs on the sauna deck in shower stalls. Biodegradable soap is available at the sauna for washing after soaking up the heat. Please use the provided soap and rinse off before jumping into the lake from our sauna lake dock that is installed during the summer months.

One of our goals here at Toolik Field Station is to limit our impact on the surrounding environment that we study. Being this far remote has some challenges, and while we can't be 100% sustainable we can have measures in place that help us be greener and reduce our impact. Here are ways how you can help us achieve this goal.

Power Conservation

Power loads that supply the station are supported by a series of generators that run on diesel fuel. During the summer season, the station goes through a lot of diesel to operate and support a high population. There are a few things residents can do to help conserve power:

  • Always turn off lights when leaving a room.
  • Always turn off power on equipment that is not in use. For example, all Weatherport tents and most dorm rooms are heated with individual heaters that use up a lot of energy. These heaters can heat up a room very quickly, so when you leave your room during the day please make sure to shut down your heater
  • Make sure doors close completely behind you.

Water conservation

Water conservation is a high priority at the station. TFS has no water treatment facility, thus all sewage and wastewater must be stored and trucked to Prudhoe Bay for treatment at great expense. For this reason we limit showers and laundry to a minimumThere are a few things residents can do to help conserve water:

  • Limit showers to two, 2-minute showers a week, and laundry to one load every two weeks.
  • Use the outhouses "towers" around the station, instead of flushable toilets

Tower fun


Trash management

We separate trash and recycle at best as possible. All the trash bins around the station are labeled for recycling, and "burn" vs "no burn". 

  • In the summer when the station population is high we incinerate burnable trash produced at the station - food waste, paper products, and other safely burnt materials - hence the importance to only throw burnable items into the trash bins labeled "burn".
  • Note that in 2024 we are installing an industrial composter, in which all food and compostable paper products could be turned rapidly into compost. This will help us considerably decrease the amount of trash we will have to burn. Our goal is to stop using the incinerator completely, and having all non-compostable trash transported back to town for proper processing.
    • In the first year of using the composter we will only be composing kitchen waste as we learn the ins and outs of the new machine.
  • Trash is not sorted in the winter months. All trash is bagged collectively and brought back to Fairbanks for proper processing.


  • We do recycle year around though, so make sure to sort recyclables appropriately.
  • Make sure to always pay attention to recyclable items and use the right bins.
  • Note that glass can NOT be recycled in Alaska. We ask that alternatives such as plastic and metal bottles and cans are brought to came instead. With the exception of glassware needed for lab work or field work.

Hazardous waste and other lab waste 

Toolik Field Station has gasoline and diesel fuel available for vehicles and other equipment. Fuel is not included in the user day rate, and will be charged independently to a project. 

If you need fuel please request some from the Toolik Operations staff during normal business hours (8:30am - 5pm) Monday - Saturday unless it is needed for an emergency. Only Toolik staff members are authorized to pump fuel for residents.

Please check your fuel gauge on Saturday. Toolik Staff do not start work at 8:30 am on Sundays, please respect their time off and fuel ahead of time. 

If you plan to acquire fuel for your project vehicle(s) at Toolik Field Station your project must establish a fuel account prior your visit to the station .

 Fuel tanks

Toolik's location and facilities offer a lot of opportunities for recreation and quality time spent as a community, when work is done for the day. Many residents regularly organize a variety of community activities that everyone is encouraged and welcome to join, from Toolik's World's famous Trivia, to breathtaking hikes, easy walks, nice runs, paddling on calm waters, or fun bike rides following the Alyeska pipeline, there's a lot for available for any types of physical comfort. 

Toolik also has a small Health Club with a treadmill, a rowing machine, weights and a variety of other equipment to stay in shape. 

Weekly Science Talking Shops occur on Wednesdays during the summer months. Everyone is welcome to attend and present.

Community input is also essential to making Toolik a better place for everyone. The users forums, organized 3 times a summer, are a good venue to provide feedback to staff and others at the station. Other meetings often happen too, whether it's a field safety training, or a discussion about diversity issues, everyone is encouraged to attend, and bring up topics they'd like to discuss or feel are important for Toolik to think about.

The weather at Toolik can be quite dynamic, and at times unpredictable. 

During the summer season daytime high temperatures range from the low 40s to 80 degrees (F). Snow usually sticks to the tundra until early to mid-June, with high afternoon temperatures and colder nights. Toolik Lake is typically ice-free by mid-June. Temperatures rise with green-up during late-June and July. Snow is possible at any time during the summer, though it won’t stick for long. A majority of the annual precipitation falls as rain during the summer months. Temperatures begin to decline again in early August, with nights falling below freezing. Snow begins to fall and sticks by mid-September. Toolik Lake usually freezes over by early to mid-October.

Snow can stick to the ground for the rest of the winter as early as early September, and temperatures drop quickly from there. It can get really cold (-40F or colder) with sustained high winds. That, combined with complete darkness from mid-November to mid-January, makes winter outdoor work challenging. Fieldwork should be carefully planned beforehand, and team members should be prepared with the adequate gear.

Toolik Field Station is home to an abundance of critters -- large and small. If you'd like a sneak-peak at what you will find or revisit an old friend, check these guides:

*Mosquito Warning*

The mosquito population on the North Slope is very abundant in the summer. Mosquitos begin emerging in early June, become most fierce during the month of July when hatchings are smaller in body size and much more numerous, and start dropping in early August. Although annoying, Alaskan mosquitoes do not (yet) carry harmful diseases. 

It is recommended that you bring a head net or a bug shirt, which can be found locally in Fairbanks, or online on sites like Amazon. Mosquitoes cannot bite through tightly woven nylon (e.g. quick-dry hiking pants), so outer layers of this material are useful. Also, it is preferable to wear light colors as mosquitoes are attracted to dark-colored clothing .

Mosquito repellent (natural or DEET) is highly recommended. Re-apply frequently but be mindful -- DEET can melt plastic! Avoid putting too much on your face especially if you are wearing glasses or on the palms of your hands when handling field gear.
