Nice loop connecting Big Basin and Butano State Parks. Can go either way -- but going up Middle Ridge is not as fun as going down. :-)

Butano Fire Road	Aug 25, 2024 @ 11:01am Aug 25, 2024	Top section of trail (first 1.5 mi after the gate you're still riding through remnants of 2020 fire. Trail is loose and sandy, poor drainage now that the trees are gone has led to ruts crossing the trail at the base of the overly drainage berms that are being treated by dirt bikers as jumps. No good lines here... Was simply happy to not pick up a flat. THAT said - once you get over the 2nd of 3 little climb and approach olmo for road everything changes. Suddenly there are 2 tracks in the road, the corners are only occasionally loose and sandy -it become the bombing run that you hoped for all along. Very fun last 5 miles to the gate at the bottom.
Johansen Road	Dec 4, 2023 @ 4:18pm Dec 4, 2023	This "trail" (actually a fire rd) is open and rideable, although there is still some forest cleanup work taking place, with some intermittent twigs and other debris present. Nothing that's a ride-stopper.
Middle Ridge Road	Dec 4, 2023 @ 4:09pm Dec 4, 2023	The section of road between Butano Rd (at the North end), south to the junction at elevation 2044 is mislabeled here. It's not Middle Ridge rd, but rather Johansen. The northern-most end of Middle Ridge begins at the jct at elev. 2044, and goes south to the jct w/Gazos Crk Rd. This is per the official state parks map at https://www.parks.ca.gov/pages/540/files/BBRSP_WebMap_17x11.pdf
Gazos Creek Road	Oct 3, 2022 @ 7:45am Oct 3, 2022	The road is open and in good condition. Nice way to survey the forest’s recovery from wildfire.
