Compared to Colorado's drive up options Bend is pretty poor. Tumalo is a nice little half day powder stash which is getting some heavy use these days. Other than that, a snomobile really helps.
For a great day tour, go to the top of Bachelor, ski off the back, herringbone backwards under the rope at the catchline so the patrol don't go looking for a lost person, yo yo Kwahl Butte powder, then head back to the west side of the Bachelor catch line and take the Northwest lift back. Get a points pass so you only pay for the three lift rides.
The best part of Bend BC is spring corn, when the roads open up and the Sisters offer 5000' vert runs with easy access. It will last well into July this year.
