A series of quartz occurrences located about 30 miles N of Reno.
A long, N-S trending summit straddling the California-Nevada state line. The USGS GNIS database categorizes this linear summit as a range. The majority of the mountain lies in Nevada, with the western foot in Lassen County, California. The quartz occurrence(s) lie on both sides of the state line. Collectors have come to refer to these quartz occurrences simply as "Hallelujah Junction," despite the fact that that town is located W of the mountain in California.
"Peterson [sic] mountain is located off of highway route 395, outside of Reno." (...) "The intersection of 395 and 70 is called Hallelujah Junction. 5-7 miles past the junction on 395 is where you want to hit the dirt. You will see it the path, the is a janky barbed wire fence."
NOTE: "Peterson Mountain" is a misnomer.
