Technically a sub-peak of Mt Carillon, The Impala is the left-hand formation that rises up above Lower Boy Scout Lake. Despite being south-facing and excellent Sierra granite, The Impala gets few ascents from the hoard of climbers passing below on their way to Whitney and Russell. It would be an excellent warm-up peak for a team with an extra afternoon to spare.

Approach via the North Fork of Lone Pine Peak - if you camp at Lower Boy Scout Lake and go no further, you should not need the special Whitney Zone permit. Tell the permitting office that you are climbing a sub-summit of Mt Carillon. If you are climbing this enroute to Whitney or Russell, then Upper Boy Scout Lake makes for a better approach/return.
The best approach is from the sandy bench beneath the Russell-Carillon Col, from Upper Boy Scout Lake. If you are climbing without a Whitney Zone permit and staying within the letter of the law, you'll need to ascend from Lower Boy Scout Lake up the gully seperating the Impala and the Springbok before traversing left on ledge to gain the base of the Impala.
