This peak is located about a mile northeast of Cervidae Peak. It is another good training peak to climb early in Spring since it is close to Boise and is free of snow often as early as February. The standard route utilizes the peak’s South Ridge. The peak can be climbed from almost any direction. I climbed it by following the connecting ridges from Cervidae Peak and then descended the South Ridge. Michael Tilden added a more difficult way to climb the South Ridge to website. Read about his route at this link: Till Dawn Ridge. Dan Robbins’ trip report is linked below. USGS Arrowrock Dam
[(C) Middle Fork Boise River Road, FS-269 Page 154] Follow Idaho 21 from Boise toward Idaho City. Just after crossing the high bridge over the reservoir turn right onto the Middle Fork Road heading towards the Springs Shore Marina and Atlanta. After 3.6 miles, pull off the road and park.
South Ridge, Class 2
The south ridge of Macks Peak starts between the two ponds on the north side of the road. Climb north up the ridge to the summit. A rocky outcrop sits on the ridge top part way up. It can be bypassed on either side.
