Access: Mt. Catherine is located on the southside of I-90 from the base of Hyak.
Route Description: ff the summit you can find some nice wooded runs heading north. They are short and then you have to navigate getting back out to Hyak. In my few trips here I have yet to find a great run and thus it has fallen off my radar since the price of entry is high. It does look like there could be some nice steep runs on different aspects if you took time to explore the mountains and could navigate the cliffs.
