1. Thompson Lake isn't even close to the most remote lake in the Uinta Mountains. For example, lakes like East Slide Lake and Wild Goose Lake are far more remote.
2. The boulderhopping really isn't that bad. It's well worth the trip.
3. There are some nice campsites just east of the lake.
Thompson Lake is off trail, but it's one of the more popular off-trail lakes (but far less popular than trailed lakes!) and
well worth the trip. Says Scott Patterson
This is the most remote lake in all of the Uinta mountains. It's a hellish 1-2hr boulder-hopping steep hike to get to the lake with NO trails or places to camp. Reserved for only extreme mountaineers. Says Jdog
