I wish I could figure out how to post pictures from my phone on here. I have a lot of berkshire east shots from this winter. Anyhow.... I would think berkshire east attempts to keep skiing through March. I don't have any insider information on it but in years past they have opened for one weekend in April. The natural may be gone by end of next week but the manmade will stick around for a long time. I made turns on Comp in early May 2015 and again in 2018. Barring any major warm spells I'd think the will close with a decent amount of terrain still skiable as they have buried the mountain in snow since the temps dropped mid Jan. They transition rapidly from skis to bikes, quicker than from bikes to ski. I have never seen the ski area as busy as it has been this year. I was up there dropping my son off yesterday and was surprised how busy it was mid week, mid day after school vacation week. I doubt people stop showing up especially if were harvesting spring corn most of March.
