"Manzanita": Sand road running from Jacks road down the ridge and generally north east to the Merrill Property where it dead ends. Fairly flat gradient along length of trail.. Most segments only have short sections of soft sand and the road is otherwise firm sand. It has been covered with straw and is becoming a single track trail. Most of the use occurs from Jacks Road to Trail 39 and little use is seen below Trail 35. Bicycle speeds average 15 mph.
Green Square Multiuse road. Bi-directional use: Bicycle>Foot>Horse
