FYI: Trail won't be closed but if you're up there during the week you may have delays.

PS: Hazard tree work is not the same as the clear cutting you see around Summit. For an example of what to expect, check out Spruce Creek and Crystal creek rd just south of Breck. They did hazard tree removal there last year.
