“GH 74-Connects Tiger Road near the dredge to Galena Ditch and ZL trails topping out on Heinous Hill.”
— D L
Summit Gulch Road (GH 74) begins on Tiger Road across the road from the dredge parking area. It is useful as a connection to, or between Galena Ditch Trail
Climb initially from Tiger Road, passing Galena Gulch Road (GH 77) on the right. Pass through a drainage, climb past a home on the right then another drive on the right. Look for Galena Ditch Trail
on the left through a timber chicane.
A 1/2 mile above Galena Ditch Trail
the road connects to ZL
Trail at another wooden chicane on the left side of the road.
Above the ZL
Trail junction, Summit Gulch Road becomes increasingly steep, rocky and nearly unclimbable. The road passes through a trail intersection on the right with Summit/Galena connector, which leads back to Galena Gulch Road.
After passing a junction on the left with Spruce Road
(GH 72) the grade mellows, topping out at the top of Sawmill Road
(GH 22), Fuller Trail
(GH 44) and Spruce Road
(GH 72) - aka Heinous Hill.
Riding north the road makes an extremely loose, rocky descent from the top of Heinous Hill.
