I have llamas and like to get to Iron Bog Lake and on up to Fishpole Lake at least every couple of years. I prefer Fishpole for camping because there's better feed for the llamas and fewer people camping. After crossing Iron Bog Creek, there's a very steep spot but it's only a couple hundred yards long. It's easy after that. There are 4 small lakes in the upper basin with Fishpole being the largest. I don't know if the 2d in size holds fish but certainly there are none in the other 2 lakes. They're very shallow. There's a resident herd of antelope there that have been there at least 2 out of 3 times I've been up. The fishing seems better at Iron Bog. The 20" minimum and 2 fish limit at Fishpole is a challenge at best. I've never caught one even remotely that big.
A short, steep climb up the ridge to the west will give you a spectacular view of a lot of country and a number of 10k+ peaks.
