Both Sundance Mountain and Mount Chapin have easy slopes on their back sides that provide the most common routes up.
However, they face each other across the Fall River. I assume that a glacier once carved these slopes away where they face each other. This is Chapin from Sundance. You can easily make out Chiquita's similar-looking face behind Chapin -- and, if you know what you're looking for, the top of Ypsilon just behind Chiquita.
Sundance from Chapin is
