Did a loop starting with Hogum Divide (the obelisk), then UPWOP, Pfeifferhorn and finishing with this summit. As stated below, it is marked as Thunder Mountain on the USGS topo map which I always found a bit confusing since it was only a couple ridges away from the much more prominent North and South Thunder mountains.
I've done this Peak 10 or so times, not counting a few days that I lapped ski runs on it. Glad to see someone else calls it lake Peak, some maps have it marked as Thunder Mountain as it is listed with John's List. I like to climb via White Pine up the north ridge,travese it to the south and descend to upper Red Pine Lake making a nice loop. The east and north slopes can be great skiing if conditions are safe, I've got a few nice ski photo's I'll attach to the page.
