A few years ago I started putting together an integrated map of the destinations included (in some capacity) in the different multi-mountain ski passes. I use it to plan trips and visualize more easily what riding options are available, if I'm undecided on how I should spend my money on passes, or what region I should try to go to.
I've updated the map for 2024-2025*, and I'll leave it here in case anyone finds it useful:
*Haven't checked if any of the mountains from previous years have been removed from the Indy Pass. The others should be OK.
