DescriptionThe Mammoth Gulch Road is fairly easy and not very steep. It continues up the valley for two miles until closed by a gate on private property. The Nebraska Hill Road forks right (north) just after it leaves County Road 4N. It is a mile long to its end at the site of the old reservoir where there is good fishing and camping. A half mile farther west on 4N, the Baltimore Ridge Road turns left (south) and climbs a mile up to an old mining area.
