Fail-Safe Trees is located just to the west of Scrub, above Lower Creek Trail, to the east of North Chute and crosses Fail Safe. It's a short, south-facing tree run. On warmer days, in bright sun, the snow can get heavy quickly here because of the south-facing aspect. In the lower sections, which face more directly into the southern sky, you need to be careful looking for rocks, logs and stumps. But, it's a fun run, and the run all the way from the top of Chairlift 4., taking Mercury. to Fail Safe Trees is a favorite of mine. Mercury's a cruiser that won't tire you out too much, and the pitch gradually steepens as the trees gradually thicken in the transition from Mercury to Fail Safe Trees.
