Mt. Agassiz and Mt. Price in one day  Sucess!

5 of us started out at 8:45 am and finished at 8:30 pm in the dark. It was a cool day. I usually climb this via Smith or Island Lake as I have always hated the 5 mile hike to where the uphill really starts. We hiked first to Lyons Lake and climbed the rock to the right of the gully and the spires. We reached Price in about 5 hours (not bad for being 84) and had lunch. We then traversed to Agassiz, climbed the table top and descended down to Sylvia Lake. Next time I will do my usual route via Island Lakes and descend via Smith and Heather.

Lyons Creek Trailhead  Sucess!

Mt Price and Mt Agassiz via Lyons Creek Trailhead and Lyons Lake. We were on the trail by 10:30 and made it to Lyons lake by 12:30 (with a number of stops to talk with other hikers along the way). Around 1:50, after eating lunch and making camp, we continued our hike by wrapping around the West side of the lake and then following the creek to the upper part of the valley. We made it to the summit of Mt Price by 3pm and then traversed back down to the upper plateau and across to the summit of Mt Agassiz by 4pm. Party of 2. 7 miles and 3 hour 10 minutes to the summit (excluding our lunch break) of Mt Price. Another 30 minutes of hiking to make our way across to Mt Agassiz. Weather was sunny with no cloud coverage but mild winds kept the temperature from being overly hot. The trail up to Lyons Lake is well shaded. 3,275 ft elevation gain to summit of Mt. Price and probably another 250 ft for Mt Agassiz. We were able to do a bit of glacading on the way back down to Lyons Lake.

Pyramid, Aggasiz, Price  Sucess!

Pyramid, Aggasiz, and Price.

Started at Lyons Creek Trailhead. I ran the gentle uphill for the first 4.5 miles of the trail before hitting Sylvia Lake. At Sylvia Lake look straight across the far side of the lake for the only major notch in the ridge about 800 feet above you. Head around Sylvia Lake to the left and start heading straight up on rock slabs and talus. A faint trail appears when you are nearly at the top of the notch. When you reach the top of the notch the view opens up and Pyramid can be seen ahead and to the left. The trail seems to stop and start as you head directly towards the false summit below the peak. Once you reach the false summit the true peak comes into view directly ahead of you.

Head down the northeast (backside of Pyramid Peak) and stay on the north side of the ridge. This is slow going, heading across the talus on this sloping traverse staying below the ridge. Pass under the first major highpoint on the ridge and shoot for a notch before the second highpoint. It is doable class 3 scrambling to get up to this notch. From the notch the long traverse to Aggasiz is in full view. Stay on the west side (left if heading from Pyramid to Aggasiz) of the ridge. Although not difficult this is a slow traverse and will likely take some patience. When approaching the summit of Aggasiz head towards the notch to the left of the summit, then go left. Although one can pull themselves up to the summit block on the south side, the north side provides for a bit easier access in getting up to the awesome summit.

The traverse from Aggasiz to Price is simple and in front of you. After the Pyramid-Aggasiz traverse the ease of the Aggasiz-Price traverse is a welcomed sight! After heading down Mount Price you can shoot down into either of the two basins south of the summit. Both will lead you down to Lyons Lake which will become visible after descending further down in the basin. Stay to the west side of Lyons Lake where you will pick up a trail leading you down to the junction with the Lyons Creek trail. After another 4.5 miles down the Lyon’s Creek Trail you finally arrive at the Lyon’s Creek Trailhead. This hike took me 7 hours, and I ran the first 4.5 and last 4.5 miles.

N Ridge from Price  Sucess!

A short walk from Mt Price. The view was well worth it! There's a nice spot at the very top rock to sit and hang your feet over desolation wilderness.

Winter from Pyramid  Sucess!

Up Pyramid from Rocky Creek, then over to Agassiz and Price following the ridge. Snow was pretty hardpacked and very icy on the north side of Pyramid. Never needed snowshoes all day, just crampons. Extremely windy, below freezing, and great views.

Pyramid-Agass-Price Traverse  Sucess!

Second peak of the day, on a traverse of the "big three" from Lyons TH. View of Agassiz in profile is spectacular (esp from Price). SE wall is an excellent scramble, but we came down it--not up.
