Starting from the Crescent Mountain, North/South Pyramid Trailhead this loop was done clockwise. See Oregon Endurance Mountain Biking for original route and expanded version. A good majority of this loop is loamy with only a few areas of chunder. See individual trail descriptions for more information. Would make a good bikepacking loop if you don't mind climbing with a loaded bike. Water sources for filtering are roughly at miles 8 and 23.

trail	date	description
Scar Mountain	Jun 9, 2026 @ 12:16am (America/Los_Angeles) Jun 9, 2026	Trail has been cleared by NWSAW. One switchback on the west side was taken out by trees and needs works still.
Chimney Peak Trail	Jun 9, 2026 @ 12:13am (America/Los_Angeles) Jun 9, 2026	Southern 3/4 mile cleared by NWSAW. Quite a mess. Still work to be done.
South Pyramid Creek - West	Jun 9, 2026 @ 12:12am (America/Los_Angeles) Jun 9, 2026	Trail cleared by NWSAW.
South Pyramid Creek - East	May 26, 2026 @ 8:34am (America/Los_Angeles) May 26, 2026
North Pyramids	May 25, 2026 @ 7:38am (America/Los_Angeles) May 25, 2026	Lots of blowdown. We made it to within a mile of the top where there were so many down trees the trail became impassable. This trail is in serious need of some TLC.
