Koyukuk River (North Fork)

These are photos and notes from a float down the North Fork of the Koyukuk in Gates of the Arctic National Park –  a Wild and Scenic river that is entirely within Gates of the Arctic National Park.  The standard section of this float is to fly into a gravel bar just downstream from the two peaks that form the actual Gates of the Arctic  – Boreal Mountain (on the east side of the river) and Frigid Crags (on the west) – and then float 90 miles to the village of Bettles. This requires a charter flight from either Bettles, Coldfoot or Pump Station No. 5 / Prospect depending on who you can get to fly you in.

People who are more ambitious (and lack children) can take a commercial flight to Anaktuvuk Pass and then hike east to Ernie Pass and then hike / packraft down to the North Fork.  You could then get a commercial flight out of Bettles and back to Fairbanks for a (relatively) cheap Arctic trip.

We have a child so we opted for the classic mellow float – and somehow Bryn & Louis convinced us to fly their kid in too.  Bryn & Louis dropped their kid off with grandma and flew to Anaktuvuk Pass and had a wonderful 5 day trek and float down to the gravel strip where they sat up a tent and patiently waited for us to join them.  We gave them a couple days to get started then packed the children into a truck, drove 12 hours, piled into a Cessna with raft and kids and food and beverages and flew 45 minutes to the strip.

We flew in on June 15 and took 8 days to float the 90 miles.  Water levels were high so getting across the channels to reach the hiking at the start was not a possibility.  Likewise high water made the fishing impossible so mostly we just enjoyed camp life while the 8 year old’s played in the water.  It was sunny every day and temps climbed into the low 80s.  The float itself, while fast, was mellow and with the exception of a rapids at mile 7 and mile 42 (see embedded map at the bottom of this page).

We reached Bettles mid-morning of day 8, had lunch at the lodge, caught a flight back to Prospect and then drove back home tired, sunburned and dirty.

June 15, 2021 – From Prospect to Gates of the Arctic

The pilot from Brooks Range Aviation showed up at Prospect mid-morning.  Communication with Judy at Brooks Range had been spotty due to poor internet in Bettles and between poor internet and lack of cell service north of the Yukon River, we were questioning whether or not our messages were getting through.  Louis and Bryn had made it to the landing strip the night before and had sent a text via inReach confirming their location.  But the pilot eventually showed up and we packed the raft and gear into the Cessna and took off.  Given our weight he had to take two flights so I flew in first while Yvonne followed shortly afterwards with the children.

We flew northeast from Prospect – the entire flight taking about 40 minutes. It was clear and calm and after coming over the mountains between the Middle Fork and North Fork of the Koyukuk we caught our first glimpse of the actual “Gates of the Arctic”.  The Gates is a “monumental” vista where two prominent peaks frame the North Fork of the Koyukuk River.

This vista was named by Bob Marshall, a wilderness activist who explored the valley in the summer of 1929. Entering through this gate, Marshall felt as though he was entering into the Arctic, and “leaving the world of man behind”:

During most of the day the Gates of the Arctic towered directly to the north as we approached that monumental entrance to the land of Mount Doonerak , our goal. When we passed through between the jagged crest of Frigid Crags towering 4,000 feet up from the valley floor to the west and Boreal Mountain rising precipitously for 6,000 feet to the east, with the mountains only two miles apart, it seemed as if we were leaving the world of man behind and were pioneering in a trackless wilderness.

We had it a little easier than Mr. Marshall and after both flights had arrived all our gear and food (and children) were accounted for, we set about building camp and inflating boats.  It was sunny and warm – in the 70s – and the river levels were high which meant that getting across the various channels from our landing strip wasn’t really an option. So we pulled out the chairs and broke out books and drinks while the children busied themselves in the mud pits until late afternoon.

June 16, 2021 – Landing Strip to Cladonia Creek

We packed up mid-morning and set off around 10am. The water had not dropped at all so we resigned ourselves to a slow float.  Given water levels we could have easily rowed the 90 miles in 3 days – but river trips with children are not meant to be speed runs.  Off from the landing zone and down the swift river. For the first several miles the valley is all of a mile wide and we had wonderful scenery as we drifted with steep treed slopes dropping almost to waterline.

The only people we saw on our trip were our friends Sarah & Chris who dropped in to say hi on the morning of our departure. #supercublife

Typical travel on the upper section of the float.

We made it all of 7 miles on our first day – making camp at the iron rich Cladonia creek, just shy of the only rapid on the trip. The late afternoon was hot and the children played in the river while the adults cowered in whatever shade they could find.

June 17, 2021 – Cladonia Creek to Tinayguk River

Another beautiful day on the river.  By mid-morning temps were already in the 60s and there was hardly a cloud in the sky.  Right out of camp we had the only rapid of the trip – Cladonia rapids – a Class II wave train with a single rock you had to miss.  We had gone to sleep listening to the roar and there was slight apprehension when we pushed off from shore.  Louis put Aven in our raft then paddled down to run it first and stand on shore watching as I rowed it with the kids.

Around the corner and right into the wave train.  The entrance was easy and the rock easily avoided – the children laughed and asked if they could do it again.  Louis snapped an awesome photo of us as we zipped through.

“Look mom – no hands!” Pumped kids in Cladonia rapid.

“Can we do it again?”

Typical beach vacation in our household. Still no bugs!

We visited the NPS headquarters in Bettles where Isabelle did a worksheet about what to take camping. She circled pizza and the park ranger told her people don’t take pizza camping.

Below the rapid the river widened and slowed and we had a easy afternoon float before pulling off on a wide gravel bar at the Tinayguk River confluence. The seldom visited Tinayguk River is of 6 Wild and Scenic rivers in Gates of the Arctic – and is the largest tributary of the North Fork of the Koyukuk.

June 18, 2021 – Tinayguk River to Mile 34 (downstream of Ipnek Creek)

Another sunny hot day with easy floating.  The river had less gradient but the Tinayguk added enough water to where overall speed didn’t decrease at all. We cooked a big breakfast and left camp late and pulled off on a wide island by late afternoon. The evening was perfect. Humidity stayed low and we stayed up watching the midnight sun arch across the sky.  I went to bed around 11pm and sunlight was beaming directly into the tent.

Breakfast. Isabelle is allowed a single small bag of personal items and somehow she fits those huge plastic dragons in them.

Of interest for this section was the only marked rapid on the North Fork.  USGS maps have a rapid labeled as “Squaw Rapid” at the outlet of Glacier River (mile 42 on my map). (Note – the rapids washed away several years ago and are now mere riffles.)

When we ran the river in 2021 it was still officially named as such – but shortly after Biden’s Interior Secretary Deb Haaland took office she formed a task force and declared the word “squaw” derogatory. The rapid was officially renamed to Glacier River Rapids in September 2022.

In late September 2022, Haaland penned an essay in the Washington Post about the process – her tweet and a link to the article is below.

Glacier River (previously called Seattle River) was also only tributary of the North Fork that produced gold. During the Koyukuk Gold Rush, where over 2000 of miners traveled to the Koyukuk region, and gold was discovered on Mascot Creek (a tributary of Glacier River) in the fall of 1902. Over one hundred thousand dollars was mined in the first year and mining continued at the site until the late 70s.

Following up with the historical aside about the Koyukuk Gold Rush is the “thrilling” account of Mrs. Hewitt who accompanied miners to the Koyukuk in 1900.  While following a group of miners she got separated from her group on a branch of the river and ended up spending the winter at a “deserted Indian iglow built of wood”. Her account can be found in the Jefferson County Graphic – a newspaper out of Morrison, Colorado that ran from 1900-1908. This epic needs to be a movie!

Seattle, Wash., Aug. 27. – A thrilling trip down the Koyukuk river recently, fell to the lot of Mrs. Hewitt, wife of a Chicago physician, now at Nome Alone and lost for months in a dreary waste, she managed to reach the Yukon river on a log raft. There she was rescued by the river steamer Hannah picked up and sent to Nome, to her husband.
Mrs. Hewitt left Chicago two years ago to join her husband. He was located at St. Michael at first, but afterward went to Nome. Late In the fall she reached Seattle and started to Dawson with a party. When they reached Fort Hamilton they heard of rich strikes at the headwaters of the Koyukuk and started across country to join the rush for that place. After reaching the Koyukuk, Mrs. Hewitt became lost on a branch of the river.
With her dog team she made frantic efforts to get back to camp, but only succeeded in further bewildering herself. Finally she was compelled to camp at a deserted Indian iglow, built of wood. The party she was with, made efforts to find her, but did not succeed, and about the first of June the river breaking up, she constructed a log raft and floated down 750 miles to the Yukon.
During the weary months she was lost and alone her courage never failed her, but when she reached Nome she gave out completely, and is now a physical wreck.

June 19, 2021 – Mile 34 to Mile 48 (downstream of Rock Creek)

On the 19th we finally had clouds and cooler weather.  A front was building to the east and with the cooler temps the mosquitoes came out of hiding. Knowing a storm would hit by early afternoon we packed up camp and left earlier than usual in the hopes of pulling off before the rain started. Even after departing from camp the bugs followed us out on the river and we rowed for part of the day with our head-nets on.

We floated until the clouds threatened to open up.

Setting up camp with dark clouds all around.

A thunderstorm rolls down valley.

Finally wet enough to build a fire big enough to burn trash. Normally I have no issues packing out all trash but in remote regions we burn smelly trash to decrease the chances of attracting a curious bear.

We made camp before the storm hit us. The clouds built, thunder rolled and lightening bounced off the peaks just west of camp, but the storm never hit camp in full. This was our last night in the mountains and we savored the view of peaks above camp.

June 20, 2021 – Mile 48 to Mile 70 (3 miles upstream of confluence)

The morning 20th was cool day with scattered clouds but by midday it was once again hot and humid. By midday we left the mountains and floated out into the broad wetlands south of the Brooks Range where the river transitioned to wide and lazy. The mountains could still be seen in the distance but surrounding us and to the south were the wide open flats of Interior Alaska.  25 miles to our south lay the wetlands of Kanuti National Wildlife Refuge –  a 1.6 million acre boreal ecosystem preserve that is seldom visited by people other than those that live along side the refuge in remote villages.

The boreal ecosystems south of the Brooks Range are have been shaped by summer wild fires and in the afternoon heat, storm clouds built over the river. We pulled off in late afternoon just before a storm rolled through camp.

More rowing lessons.

The storm dissipated by 10pm and when the clouds burned off a rainbow materialized above camp as we turned in to bed.

June 21 / ~Mile 80.

June 21, 2021 – Mile 70 to Mile 84 (8 miles downstream of confluence)

Summer Solstice never really dawned where we were because the sun never set – but we woke to calm warm skies with only a handful of scattered clouds.  For Alaskans Summer Solstice is the height of the year – we revel in the endless daylight and celebrate the light and warmth of summer that will be over all too fast.

This was the perfect day. We left camp in late morning and floated down a lazy river under a hot sun.  The final few miles upstream of the confluence were slow and lazy and when we reached the confluence we paddled to the south side where we pulled over and walked along the muddy beach looking up the North Fork that we had just left and the Middle Fork that joined from the east.  With the two rivers converging the flow almost doubled and suddenly we were on the mighty Koyukuk – one of the mighty rivers of the Yukon-Koyukuk region with a basin size of 32,000 sq mi.  The Koyukuk is the last major tributary of the Yukon, before the Yukon empties in the Bering Sea, and in late summer the discharge near the Yukon confluence can be 330,000 cfs.

We floated a few miles further and then pulled off to investigate a large gravel bar for a possible campsite.

Serious breakfast selfie.

Bryn cooling off. It was hot!

The gravel bar ended up being a magical camp.  The spring break-up have carved waist deep channels into the gravel bar and they were now filled with crystal clear water.  The sun had baked the pools to where the water was warm enough to swim – and not typical Alaska swimming (jump in/jump out) but warm enough to actually soak in comfortably.

We set up camp and then spent the afternoon soaking in the pools until late evening when we finally reluctantly went to bed knowing that tonight was our last night on the river.

June 22 / Bettles.
Bettles Lodge was build in 1951. It has served as a hotel and restaurant and was listed on the National Register of Historic Places in 1997.

June 22, 2021 – Mile 84 to Bettles

And then the trip was over.  The final 6 mile float to Bettles took about an hour and by noon we had packed up the raft and Brooks Range Aviation shuttled our gear to the airstrip.  We ate lunch at Bettles Lodge and then climbed into the Beaver and drifted overland and back to Prospect where our truck was parked. After we unloaded our raft the pilot asked me if I could help load a refrigerator into the plane.  Somehow we made it fit.

Last day on the river.

Bettles heat wave!
