Searched for benchmark stamped 'E 287' at 16:30, 21 November 2012. The benchmark was not located, but may still be in place. The location described for the mark is between McCall Avenue and an actively farmed vineyard. The mark is described as being "about a foot lower than the track", however the area, which is used as a farm road, has been built up to be about level to six inches higher than the track. No new coordinates were taken.

There is a Fresno County Brass Cap Monument (FCBCM), No. KM69, about 20 feet northeast of the described location, about 1 foot northwest of a power pole. Said FCBCM is NOT GT1425.
