Harper Mountain Ski Area is located near Thompson-Nicola, BC. The trail is primarily used for downhill skiing and is accessible from December until March.
Been here a couple of times over the years - I lived in Kamloops, BC (about 15 mins away driving) and the company I worked for put on an annual function there each February. As far as ski resorts go it is pretty much right down the middle quality wise (I have been to Grouse Mountain and Cypress in BC's Lower Mainland and they are a little more upscale). Still not too expensive and a nice place to go especially if you like tubing - which they have a great run for.
