Bull Caribou Denali


Brooke’s Range, north Dalton Highway

In May 2006 I spent just 24 hours in Alaska and travelled on the ferry from Haines to Skagway during a trip around the Canadian Yukon. I saw a few Harbour Seals, but not the suposedly common Dall’s Porpoise nor the Mountain Goats that are often seen as the ship comes in to Skagway.

I returned for 5 days in July 2015, with my two kids. Our – OK let’s be honest my – targets were Alaska Marmot and Collared Pika, with Lynx a half-hoped for long-shot

We flew into Anchorage and drove 6 hours north to Fairbanks for the night, before heading up the Dalton Highway the next morning. As others have mentioned, the Dalton Highway, at least in July, is far less rugged a road than many of the brochures would have you believe. A lot of the first 200 miles is paved, and other than a very occasional piece of grit hitting the windshield from a passing truck there was little to be concerned about. Nevertheless, most (all I think) of the major car rental agencies forbid you from taking their cars up the road, so I decided to hire a vehicle for 48 hours from Arctic Outfitters in Fairbanks. It was not cheap, but it was cheaper than the competition and the second spare tire, CB radio and peace of mind was sort of worth it.

It took nearly 8 hours’ driving from Fairbanks to get to the start of Alaskan Marmot habitat, just after Atigun Pass and the peak of the range. The drive up was pretty but the only mammal of note was a distant Black Bear. I’d researched Marmota broweri sites beforehand and got some great help from Aren Gunderson at the University of Alaska Museum. Aren is one of – if not the – leading expert on this species (see his work here). It was Aren who helped Dave Robichaud see this species during his 2006 Marmothon.

Midnight camping at Galbraith Lake, Brooke’s Range

Aren recommended checking two sites for easy marmot spotting: a small gravel pit just north east of Galbraith Lake, and another site 10 miles up the road. I chose the latter, stopping first to look at the site Vladimir Dinets and John Fox scored at in 2010, on the east side of the road at mile 259. I got a distant look at an Alaskan Marmot here, but got much longer and better looks at the colony that Aren had recommended, near mile marker 283, a mile or two south of Toolik Field Station.

Directions are as follows. As you travel north up the Dalton Highway, look for a pipeline service track off to the right (east). These side roads are infrequent and I think this is the only one between mile 280 and the Toolik turn-off. The road is gated, so you need to leave your car, walk under the gate and up the hill under the pipeline. The marmots are on the low rocky hill in front of you, but access is easiest if you follow the road as it turns to the north and approach the hill from the northern slope, rather than cut across the boggy tundra in front of you. I found several Marmots easily here at about 9 p.m. Well worth the cold silence from my daughter when I got back to the car, who had refused to set food on the mosquito ridden tundra, but was unimpressed at being left to the mercy of the Grizzlies. Oh well.

Walking back to the car I saw a family of three Red Foxes playing in the long grass, looking lovely in the soft evening light. The soft evening light lasted until 3 a.m. by which time it was blazing bright again.

Red Foxes, Vulpes vulpes

We camped the night at Galbraith Lake, where there were a few Arctic Ground Squirrels, and continued up to mile 301 the next morning to look for Dall’s Sheep on the north face of Slope Mountain. We saw 4 distant animals.

I’d wanted to drive on another 40 miles to look for Musk Ox around the Happy Valley area (a regular spot for them), but realised I would not have had enough gas to have gotten back to Coldfoot, the first fuel stop heading south, and didn’t have the time nor desire to drive 2 hours north to Deadhorse to get fuel only to turn around again. So we drove back to Fairbanks, dropped off the car at about 8 p.m. and drove another 2 hours south to spend the night near the entrance to Denali National Park.

Denali National Park

Bull Caribou, Rangifer tarandus, Denali National Park.

I had wanted to visit Denali National Park for as long as I have been interested in mammals. I wasn’t disappointed. The wildlife viewing is exceptional. And even though it was peak season, the compulsory use of park buses along most of the only road through the park meant the park didn’t feel too crowded.

First, a little on the logistics. During the high season, June – August, visitors to the park are generally not allowed to take their own vehicles past the Savage River campsite at mile 12 of the park highway. An exception is made for those camping at some (not all) of the campsites further into the park.

I booked a space at Teklanika River Campground, which is the furthest campground one is allowed to drive to. If you are staying at Wonder Lake for example, you have no choice but to take the bus. Even when you are camping, you don’t have carte blanche to drive up and down the road: after checking-in at the visitor centre you are given two permits to cover one trip up and one down the road. The checkpoint was shut at midnight when I eventually arrived at camp, so no one checked my permit on the way in, but the return ticket was collected when I left the next morning.

Grizzly, Urus arctos horribilis

Shuttle and tour buses traverse different bits of the park road all day and you can get off one, walk a bit or a lot, and then hitch a ride on another if there is space. We had pre-booked onto the last shuttle bus that day that drove to the end of the road (Wonder Lake) and back. It left the visitor centre at about 10.30 a.m. returning around 9 p.m.

Caribou, Rangifer tarandus

We didn’t see many mammals until we passed Teklanika River, after which we saw our first Grizzly, the first of at least ten that day. Other mammals included a big Bull Moose, several Caribou, some photogenic Dall’s Sheep and plenty of Arctic Ground Squirrels and Hoary Marmots, especially at the Eielson Visitor Centre, plus a Red Squirrel at Wonder Lake. There were – not surprisingly – more animals moving around during the late afternoon on our return trip.

Dall’s Sheep, Ovis dalli

The bus driver stopped for 10 minutes at Polychrome Pass to indulge me in some Pika searching, but we didn’t see any.

It was frustrating having to watch wildlife from the bus, but there is precious little alternative in Denali, unless you try to win the lottery to drive the park road in either May or September.

Arctic Ground Squirrel, Spermophilus parryii

We’d left the car at the visitor centre, so we could drive to the campsite late: the boreal forested stretch of road, between the gate and Teklanika, is the best habitat for Lynxes but they remain rare and will likely do so until Snowshoe Hare numbers peak again. We didn’t see a Lynx, but did see three more Moose along the road.

Hatcher Pass

Collared Pika, Ochotona collaris

We left Denali the next morning, and drove the four hours south to Hatcher Pass, where John Fox had easily found Collared Pika in 2010. They remain easy to find, and we saw several within five minutes of arriving at the small rocky bowl just past a sign welcoming you to the Summit Lake Recreation Area (when coming from the east).

There were Hoary Marmots here too.

Hoary Marmot, Marmota caligata

If for some reason you dip on the pika then try the Hatcher Pass Lodge, a few minutes east of the lake. There were pikas, ground squirrels and marmots living under the chalets here and we saw several during a pleasant stay. In fact, when snow is on the ground, it might be an easier place to see the pikas than the pass, as it sounded like they scavenge for scraps around the lodge.

I set 80 sherman traps around the pass that night. But despite Vladimir Dinets’s reports of a “shrew plague” a month earlier I caught nothing, though tundra species are hard to trap.


The next day we stopped at Beluga Point, on the Seward Highway just out of Anchorage, twice, on either side of a high tide. There were lots of fish around, judging by the dozens of fisherman out in one creek in particular, but we only saw the back of one Beluga.

So a short visit to Alaska but a lot of fun and scenically wonderul.  Definitely somewhere I would like to return, most probably during a different season.
