On Saturday, April 20, 2019, I Left the Bear Lake Trailhead, at 4:23 AM, for Notchtop Mountain in the Odessa Gorge, in Rocky Mountain National Park. My goal was to ascend the right of the two Notchtop Couloirs (Grade II, AI 2 to 3) located on the north side of Odessa Gorge and just west of Notchtop Mountain. I went up the left couloir last year and just felt like doing the right this year.

This year’s spring snow attempt was roughly a month earlier than I have normally done (early to mid-May is what I try for), but the advantage to the earlier start was that the avalanche information websites, like Colorado Avalanche Information Center, were still being updated. I think these sites stop updating as soon as the ski season ends. So, the CAIC had declared the avalanche danger for this day and area as "Low" above treeline: I was good to go.

This shot looks up the route from where I geared up at 7:01 AM. I started up at about 7:30 AM with crampons on hiking boots, axes, climbing harness, some carabiners, a couple runners, and a helmet.

At 9:17 AM, I stopped for a short rest and took another shot looking up the couloir. So far, other than an eight-foot section of steeper alpine ice and rock mix, this was a consistent roughly 40-degree crusty snow climb. I had noticed a couple of small branches leading off to the left going up, but I was content to stay with what looked like the main vein of the couloir.

Top of Notchtop Couloir (Right) with Notchtop East Face cornices in the background About 10 minutes from the top of the couloir, I started noticing a problem. I had assumed that this couloir would take me to the gorge rim, like the left couloir had last year; however, the cornices I was now seeing beyond the top of the couloir indicated that I was going to be at least a hundred vertical feet short of the rim - bummer!

At, 10:32 AM, I was as close to the top of the couloir as I dared to get. That rise in front of me was probably another cornice, and I didn't want to chance having it break off with me on top. I couldn’t see any reasonably safe route up to the gorge rim from where I was, leaving me two crappy options. I could down climb to one of the left branches and try again from there, or just give it up and down-climb the whole route. I decided that I had had enough fun for one day and started heading down. It took me a few minutes to get a good down-climbing rhythm going: this wasn’t a skill I had practiced a lot. Even though it was easier on the cardio system going down, meaning I could go faster with less breaks, the descent still took about an hour and forty-five minutes. The short ice and rock section was a little awkward to reverse too. It would have been a great energy and time saver to have been able to glissade, but the route was too steep to easily control my speed, and I didn't want to risk an uncontrolled tumble down the route with an occasional bounce off the rocks, much like a pinball.

Just 15 minutes down, turning to be sure I was still positioned in the center of the couloir, I noticed this great view of the north side of Flattop Mountain. I set my axes deep and anchored into them so I could take some shots. As I looked, I thought I saw some movement in Flattop Gully, centered in this picture.

Two people with skis on their packs working up Flattop Gully in Odessa Gorge I zoomed in with the camera and could easily see two people with skis on their packs working up Flattop Gully. They seemed to be moving at a good pace, so I don’t think the angle of ascent was quite as steep as it looked from my viewpoint. Still, I envied what looked like a higher level of fitness than mine.

It was about 12:30 PM when I dropped my pack at the bottom of the couloir and had a lunch Cliff Bar before heading out. Unfortunately, as I made it down to Lake Helene and Two Rivers Lake, just outside of the gorge, I had to dump my pack and go back up for my camera which was still sitting on the rock where I ate lunch. This screw-up added forty-five minutes to my hike out. Embarrassingly, this was probably the sixth time, or more, in the last 17 years that I’ve had to back-track for my camera, some adding hours to the hike. I’ll never learn. At 2:17 PM, I took my final picture showing the east side of Notchtop Mountain with the cornices lining the top. These were the cornices I saw from the top of the couloir.

I made it back down to the trailhead at 4:00 PM. My GPS showed a total distance of 8.5 miles; a total time out of 11 hours and 40 minutes; and a total altitude gain of 3,731 feet. This outing didn’t go exactly as planned, with a couple of hiccups for sure, but all’s well that ends well, and it sure was a beautiful day to be in the mountains.
