Snow station

The base and the outlook for this lot come from the Diamond Lake station, 167 ft below the lot. A station below the lot reads low and melts out early, so the snow here is usually deeper and lasts longer.

The place

Before you go

A Sno-Park permit is required to park here from 1 November to 30 April. Whether the lot is plowed is not tracked here.
