Took a quick look at a single day ticket for January 2025 at a few less well known places out west. Not surprisingly, Saturdays are always $10-25 higher than Sundays. Fridays are usually more than Mon-Thu. Didn't find any Saturday prices over $150 for an Adult, most were $100-110. The age at which a teen has to pay the Adult price varies quite a bit. With demand pricing, can't just look at a table of lift ticket prices for many places these days. In most cases, there is a lower price 48-72 hours in advance.
I checked Brundage, Tamarack, Bogus Basin in Idaho; Bridger Bowl in Montana; Monarch, Wolf Creek in Colorado. I'll be using the Indy Pass at Brundage and Tamarack next March, with a day at Bogus after we drive back to Boise. Bogus and Bridger are probably the two most successful long-time non-profits in the USA. Monarch and Wolf Creek continue to add terrain slowly but surely. Of these places, only Tamarack has a resort "village" with modern slopeside lodging. That trip includes a couple of friends who are intermediates who need to be able to start late and/or finish early.
Fair to say that most of the people who are regulars at the places ai checked are locals.
I talked to plenty of out-of-state folks at Wolf Creek a few weeks ago. Mostly from OK and NM. There were plenty of TX license plates in the upper parking lot. The closest lots filled up by 8:45 on the weekends. There were first-timers taking lessons mixed in with the knowledgeable advanced folks who headed over to the Alberta side (essentially all black ungroomed terrain) first thing in the morning on the day after a small snowstorm.
