Check out the course put on by Steamboat powdercats- I did it 2 years ago and it was excellent (it's the second Avy course I've done- the 1st one being a National Ski Patrol course in 1992). It's a two-day weekend, and the cat takes you back into safe but realistic areas on Buffalo Pass to learn how to dig pits, read snowpack and read terrain. They can also simulate a deposition zone with crazy realism, because they can bury a pack with a transceiver in and and run over an entire area with the cat tracks. The pack is gone, and the snow is compacted over a wide area and difficult to dig into, just like a real slide.
All the instructors have been through the Silverton instructor's course, and they deal with high avy terrain nearly every day. I highly recommend it - it also happens to be very reasonable at $275 for 2 1/2 days.

I wouldn't wait too long to register, because it will fill up.
