Skied at Timberline March 29/30. Weather was sunny, warm & beautiful. Everything was open , including Palmer lift. Snow got soft in the afternoon. Night skied on Saturday - snow faster, but I find Timberline a little dark at night. My son & I played around Terrain park on Sunday. Agreat Spring weekend with plenty of snow (although a little soft at times).
This weekend should be good conditions - Snowboard competition at Timberline.
Meadows is done with night skiing for the season. SkiBowl is now only open on weekends, but I don't know if they still offer night skiing. Can't tell you about Timberline 'cause I only go there when the other's have closed.
Update. According to Timberline's web site, they will continue offering night skiing until the end of April, weekends only. More, and probably better, details may be obtained by calling: 503-222-2211.
