Mary Ann Furnace Trail: 3.5 miles
From the trailhead along Black Rock Road, the trail begins on a boardwalk through the wetlands of Black Rock Flats then climbs through a tall deciduous forest that borders old farm fields and comes to a Y. The left trail eventually follows the shoreline of the lake. The right trail climbs to the top of the hill and gives a view of the campground. Both trails interconnect and connect to a spur that leads to the campground.
The geocache hidden at the posted coordinates is a regular geocache, however, it is also part of the 2015 (Phase III) Spring Grove GeoTour (SGGT), a project designed to promote the many businesses and other places of interest in the Spring Grove Area. The SGGT utilizes the growing interest in geocaching to assist both residents and visitors to the area in learning more about the unique attractions.
