Thunder Pass

Post by Wandering Daisy » Sun Dec 15, 2019 3:07 pm

Anyone been over Thunder Pass, the one that goes from the lakes above Reflection Lake directly into the upper valley of Casper Lake? It is supposed to be Class 2 but looks harder on Google Earth.

I went over Thunder this year. I saw it listed as class 2, class 2 axe required, and class 3. I agree with all 3 ratings. It appeared to me that there was a diagonal path through the center of the headwall that might go c2. That, however, required crossing a steep enough snow field. I didn't bring gear so I went up the first chute to the right, which was a loose mess that got steep at the top. Wouldn't take my partner over it, but I'd do it again. I could probably send you some pics.

WD,

Andy D put a video on youtube of his Great Western Divide trip. Here is the link:

Fast forward to about 16:30 to see his approach to Thunder Pass from the south. He decided to not go down the north side; the video shows some of the steepness on the north.

If you use the button that says "full editor and preview" you can attach photos by clicking and dragging them into the "Topic review" pane or you can use the "add files" button on the attachments tab under the Topic review pane.

I remember lots of small, loose talus on the north side.
My trip report doesn't say much about the pass, but it has a view from the north at: http://www.sierrahiker.com/ThunderCol/index.html

So are the lakes below the pass on the north side worth a side-trip to see? I just thought that once you get up to these lakes it is a short distance over Thunder Pass/Col to do a little loop through upper Kern. I have been on the south side when I climbed Thunder Peak so am familiar with what that is like. Perhaps a better plan would be to just day-hike to the lakes and then drop to Reflection Lake.

Thanks for the information. I am not fond of really loose stuff so perhaps this one is not for me.

The lakes leading to Thunder pass are rockbound and don't offer much - but austere solitude. The large-ish lake before Longely pass is quite beautiful, with excellent camping. I followed the string of lakes towards T pass but wish I hadn't, there's some large talus in the way. There's a more direct route between the lake I refer to and T pass to the south, over a rounded ridge. Next time.

Right in the middle, from right to left and sun to shade, I think there's a c2 path.
