This site was the designated camp for boys aged 14 or more, who were assigned  their own provisional leaders and an “older boy” program.

This plan seems to have varied depending on the leadership available and the number of older campers.  Some years the site was made available for the growing number of troops coming to camp with their own leaders and in others it was again used as the site for older campers.

When the “Senior Camp” was built across the Tenny River the only access to it was by rowboat or by the Tenny River Road off route 85.  With a capacity of 24 scouts and several leaders, better access was needed so a ferry know as the "Tenny Belle" was established. 

In the late fifties Waterfront Director Don McLean was also assigned as Explorer advisor for the older boys in Tenny. They organized as an Explorer post, with leaders elected and programs planned by the boys.  One of their projects was cutting and blazing the Red Trail , which then led from the Tenny landing up the riverside to the property line ( a “Dutch wall” of earth) then inland to the road and on to the lake shore at the point of land beyond the Tenny site.

In the sixties, with increased troop camping, the need for a senior camp no longer existed so the site became available every week to troops coming to camp as a unit.
