Climbing and access information for this peak is on Pages 149-151 of the book. Please note that the book incorrectly spells the peak as “Steele Mountain.”
I have climbed this peak 4 times. It’s a good day trip from Boise. I have only climbed the West Ridge. There are 7 routes in the book. USGS Rocky Bar
The West Ridge of Steel Mountain is on the left skyline.
Midway up the West Ridge. The ridge is a steep pull. The bottom section burned around 2010. Once you get above the burn area, the trees thin out and you find impressive granite outcroppings that can easily be skirted.
The West Ridge Route is steep but, for the most part, the footing is good. The lower section of the route burned recently.
The North Summit of Steel Mountain is an enticing destination.
