 The Youth Conservation Corps , Boy Scouts , and the Oregon Department of Forestry built the trails leading to the tops of the Table Rocks in the early 1980s , around the same time the plateaus were being nominated as an Area of Critical Environmental Concern . In June 1999 , only two small trees were cut when Shady Cove contractor Randy Hodges rerouted a 3 ⁄ 4 @-@ mile ( 1 @.@ 2 km ) section of the Lower Table Rock trail to accommodate the growing number of visitors . The project involved decommissioning the old section , expanding the parking lot , and installing 2 @,@ 200 feet ( 671 m ) of new trail . Measures to protect the trail were implemented , such as installing rock <unk> and a layer of shale gravel over the clay .
