Mountain Ops (461.400 D245 FB2) and Condo/Hotel Ops (462.100 D245 FB2) are still accurate and active this year. I can't verify the channel numbers, as this was based on information from many years ago (probably about 20 years ago). Snowmaking (463.300 D245 FB2) was active until last year, but I don't think I've heard it this year. I also can't verify what's being used for mobile / simplex comms, as I'm just too far away.
kjl13, curious to see what you were able to confirm.
