Grizzly Flat North Trail / Middle Road: 3rd Visit

2 years ago

Another stop on a bike ride to check out an old road I saw near the middle of the Grizzly Flat / North Trail in Upper Stevens Creek County Park. Main goal was to locate 2 features that show up on the hill shade map, one a steep area along the south side of Branch D that may have slid and taken out the old 1897 road. The other feature seems to be a steep gully beside the road that also runs down to Branch D. Way points at these 2 features helped in lining up the topo may over the hill shade map.

A few things to look for in upcoming visits are if the barbed wire fence is only along the road or if it runs in a straighter line between the curves in the road (i.e. a property boundary). Also, need to check for signs of old tree stumps or other signs of logging in the area. This road seems to have been built for decent sized trucks, judging by the large radius curves, but not sure of the purpose.

This road doesn't appear on any maps. It looks like it may been constructed around the same time as the Grizzly Flat road. Grizzly Flat North Road first appears on the 1961 USGS topo map.

There appear to be at least 3 roads that come together at the bottom of the Branch D canyon. 2 of them seem to be quite old based on their minimal construction. Then this road seems more modern in terms of wider radius turns and that it joins up to an existing road. But then the question is, what was this built road for? Were the 2 older roads in the canyon still in use when this road was built? If not, then why did this road go down to the same area that the 2 old roads seem to meet up in? Maybe this road was abandoned when the county acquired this land for the county park in 1965.

Hopefully can make it to the bottom and see if there's any sign of these old roads connecting as it appears on the hill shade map, I think I got within 100 yds/m of the bottom.
