You are looking for a camoed poly jar hidden near the crossroads of two highways, an old one (US 6) and one not yet built (High Desert Corridor).
US Route 6, also called the Grand Army of the Republic Highway, is a main route of the U.S. Highway system, running east-northeast from Bishop, California to Provincetown, Massachusetts. Until 1964, it continued south from Bishop to Long Beach, California and was a transcontinental route. The route ran through the cities of Palmdale and Lancaster along the current alignment of Sierra Highway, except for a short portion in Palmdale that ran along the alignment of 6th Street East through what is now the Palmdale Transportation Center. An existing reminder of this highway designation can be found on a sign along southbound CA Route 14, a successor to US 6, between the Ave S and Angeles Forest Highway exits.
Major William L. Anderson, Jr. of the U.S. Army recommended that US 6 be designated the Grand Army of the Republic Highway, honoring the Union soldiers in the Civil War. The Sons of Union Veterans of the Civil War began pushing for the name in April 1934. Massachusetts, the first state to apply the name, passed a law to do so in 1937. California did so in 1943; it was not until at least 1948 that all states had agreed. The highway was formally dedicated at the Long Beach end on May 3, 1953.
The High Desert Corridor (also referred to as the 138 bypass) is a proposed freeway that will connect the Antelope and Victor Valleys. The Palmdale end will run along Ave P-8 (Technology Drive) southeast of the Antelope Valley Mall; passing south of the Desert Aire Golf Course while staying north of Palmdale Boulevard, eventually crossing US 395 & I-15 and terminating somewhere in the Victor Valley. As of Dec 2007, this project still has no start date and how it will be paid for is being debated by politicians. For a map of the proposed route click here.
The listed coordinates will take you to a commemorative US 6 highway marker that was erected December of 2006. Parking can be found in a parking lot north of the coords, or due south in a dirt lot. There is no physical cache at this spot. On the marker, count the number of reflectors on the number 6, this equals X. The cache can be found at N 34 35.886 W 118 07.X7.
PLEASE DO NOT RUN ACROSS THE HIGHWAY, JUMP ANY FENCES, OR CROSS ANY RAILROAD TRACKS ON FOOT TO FIND THIS CACHE.
