Trespass Permission : The level line was established on Mesa Valley Farm property with permission of the owner at the time, but the farm has not been inhabited for several years.

Directions: From t he intersection of Interstate 5 and the Frazier Park Road between Gorman and Lebec, proceed west on the Frazier Park Road about 2 miles to a gate and an unmarked, unsigned dirt road on the south side of the road. The gate may be locked, but is usually ope n. The road proceeds south about a mile to some power line stanchions. The north-south leg of the level line is along the east side of the fence that is nearly parallel to and about 50 m west of the power line.

Comments: This irregular array crosses a wide zone of fault strands in the San Andreas fault zone northwest of Gorman. Bench marks MV07 through MV24 are on property belonging to Mesa Valley Farm. Bench marks MV10 through MV18 constitute an alignment array.

Several bench marks have been added at various times to extend the length of the line, the most recent being MV01, 02, and 03. All bench marks are Class B rod marks driven to refusal and capped with a stainless steel nipple.

The distance between two of the 24 bench marks in this array are measured infrequently with a Wild TC2000 total station distance meter. No changes have been observed among the resurveys.
