Showing grading up to 4' solid bottom for a 4' trail. Hughes Ridge Trail Great Smoky Mountains National Park Showing grading up to 4' solid bottom for a 4' trail...Mattock handle 36 long. Result of this amount of grading on a gentle slide slope is a trail 7' wide unless the dirt is scattered over a wide area. All this is unnecessary work where the slide slope is as gentle as shown here. If any grading must be done, it should not be over 2' on solid, using the earth removed for fill to secure a 4' width. When the trail is close to the top of the ridge and the trail and side slope grade is low, there are no drainage problems.Hughes Ridge Trail, II-Th-5234, Physical Facilities - Trails - Horse Trails
Showing the unnecessary grading. Where underbrush is absent, no work is necessary. Hughes Ridge Trail Great Smoky Mountains National Park Showing the unnecessary grading...on flat places like this, the only necessary work is the removal of the brush by grubbing. Where underbrush is absent, no work is necessary. Hughes Ridge Trail, II-Th-5233, Physical Facilities - Trails - Horse Trails
