Double Black Diamond	May 12, 2025 @ 8:50am 18 hours	Cleaned up a few bits on the lower part of DD below South Lost Lake Trail. Thanks to Evil and Arc'Teryx for sponsoring the Dig Day! reporter
Double Black walk up	May 1, 2025 @ 1:04pm May 1, 2025	The hiking trail in from the parking area to double black... It is starting to get rutted where bikers shred the corner between the two trails. Maybe be a tad gentle on the shared space until you are on the MTB specific trail.
Double Down	May 1, 2025 @ 1:04pm May 1, 2025	Great dirt.
Ridge Trail	Mar 22, 2025 @ 2:18pm Mar 22, 2025
Cleator Road	Feb 24, 2025 @ 9:36am Feb 24, 2025	Drove up (2/23/2025) with no problem.
