Bobcat,
Do you have any idea why there was a phone line between Round Lake and the Rho Ridge trail? The 1938 map shows it:
"Oh Boy Forest Camp" and also alternate Round Lake trail on map

I haven't seen any explanation. Obviously the line was there before the road was built. My best guess is that, back in the day when the whole area was open to grazing, there may have been some kind of monitoring crew at the lake (counting sheep was the main reason for many of the original guard stations) although it's clear there wasn't a cabin there.
