trace a connecting road

Trace a very prominent road along a ridgeline.

this looks to have been a USGS trace, but we can do much better with aerial.

I happen to know this park uses a certain size of tank and pumps with a certain size of solar panel, and this is almost certainly what these are.

A previous version of this map had a stream from the pond to La Costa Creek, but, it crossed over bare land and was not noted on the USGS map. The Bing map appears to show at high water levels that this is the intermittent stream's route. I also traced Bi

Trace photography. The previous path was a spot-on match for USGS here, and they approximated/got the stream wrong here.

Merge the two creek paths

This stream does not appear to run through, on aerial nor UGGS map, which notes the pond.
