One of the original hard men, Dave Bingham, has written Underground Idaho which also contains the latest information concerning climbing at the Fins and other local crags.

Located at the southern end of the Lost River mountain range, the Fins offer climbing unlike any other in southeast Idaho. On vertical to slightly overhung walls of immaculate limestone, most routes here feature positive edges and secure pockets. The rock is somewhat sharp, but the texture is excellent. Chances are, your tips will wear out before your forearms.
The walls at the Fins have seen significant new development as of 2012, so there are many more routes than I have descriptions for. Dave Bingham, Matt TeNgaio, and Jonathan Siegrist have been the major contributors lately. We all owe a huge thanks to these guys and the earlier developers for their hard work and vision.
Morning sun, afternoon shade. When it's too hot to climb elsewhere, excellent conditions can be found at the Fins in the afternoon and evening of even the hottest summer days.

Getting There 

South of Howe on Highway 33, turn west at a gravel pit into Eightmile Canyon. Keep right on the dirt road as it enters the canyon. If you've got a four-wheel drive vehicle, drive five miles to basically the top of the mountain and park in the established parking.
For low-clearance vehicles, you'll need to park in the lower parking (about 3.5 miles from the highway).

Idaho's hardest sport route.From first ascensionist Jonathan Siegrist's description (with permission):"The climb begins with a pumpy and cool 13a called 'Son of Discovery', before breaking dramatically right as the grips gradually decline to a sequential, powerful and very low percentage mid-height crux. One specific move in this crux thwarted me repeatedly. Pure difficulty was certainly an issue, but mainly it is characterized by an off balance, super accurate and long move.

On the upper parking: Clearance isn't necessarily an issue as a reasonably skilled driver in a Subaru can make it. If you have low-range use it, if you have a transmission temp warning light, pay attention to it, if you don't, plan to take a rest or three on the way up to give your tranny a rest (automatics). Watch your engine temp too, mine was fine on the first run up, but was the limiting factor on the second time up (hotter day). My vehicle is an AWD Chevy Express. I know one Jeep Cherokee had to turn back due to tranny overheating.

Rattlesnakes: There is at least one in the rocks just above the camping; watch and listen when 'getting rid of your coffee'. Running on the dirt road, a climber on a rest day came very close to one. It's a good idea to keep a bite extractor kit with you. See photo - very center...
