Access: Red Mountain is accessed from Commonwelth basin. To save yourself a ticket, park in the Summit West lot and walk under I-90 to the start.
The approach typically follows a well trodden trail up the basin and crosses the creek by going left where the trail splits on an obvious log bridge. The right takes you up towards the flanks of Kendall. There are other ways to approach from Alpental. You continue in the drainage on mellow terrain until you cross back over the drainage atleast once more. If done well you will find a gradual ridge that takes you most of the way up the first slope to an upper basin. A 40-45 degree slope takes you to the summit. This slope is 40-45 degrees and I only venture onto Red if the avalanche danger is low. Also, be very careful of staying clear of the summit cornice. The ski down follows closely to the uptrack and you enjoy a nice steep run, some navigating the creek, and then the luge track back to the cars.
