Comments on the location information

  • PROBABLY IN SISKIYOU NATIONAL FOREST SOMEWHERE NEAR PEARSOLL PEAK. CANNOT LOCATE BECAUSE UTM GIVEN IN CARLSON AND OTHERS PLOTS IN CALIFORNIA AND NO FURTHER DATA IS AVAILABLE. LAT/LONG GIVEN ARE FOR A LOCATION IN CURRY COUNTY THAT LIES WITHIN THE QUADRANGLE BASED ON THE ASSUMPTION THAT THE UTM IS THE RESULT OF TYPOGRAPHICAL ERROR, BUT THE LOCATION IS SAID TO BE WITHIN JOHEPHINE COUNTY
