The Lemhi Range runs slightly northwest to southeast with the highest summits located in the southern end of the range. All nine 11000' summits occupy the south end of the Lem's.

All these summits are Class 2 & 3 with the exception of The Riddler which is a Class 4.

Big Creek Peak and Flatiron Mountain are Class 2 efforts from the west while the Lopez guide book spells out the Class 3 routes.

The ubiquitous USGS surveyor T.M. Bannon claimed a couple of these summits as early as 1913,
while other peaks did not see first ascents until the early 1990's.

Peaks with an * are unofficial names, although the Idaho climbing community gives them full acknowledgement.
