03-Aug-2015 -- This was the continuation of a summer trip with several successful confluences. The day before I had visited 48N 117W. I spent the night nearby at Mountain Home and was ready for an early start.
I turned west on Highway 167 and then south on Strike Dam Cut Off Road and then made a hard right to the northwest after a small S turn at the bottom of a hill onto a dirt road. I followed that and then made a left here onto a better maintained dirt road that would eventually take me to within 220 meters from the confluence.
I hiked up a slight rise covered with basaltic rocks and the open terrain made for easy acquisition of all zeroes. It was mostly scrub and yellow and green bunch grasses with a bright green field and other agricultural plots to the south breaking up the otherwise unremarkable landscape. There were several pronghorn antelope nearby. An existing cairn was a few meters north of where I determined the confluence to be.
Post processing of the GPS data reveals that my GPS receiver was 1.0 meters northwest of the actual confluence with a Horizontal Precision of 2.5 meters. I also collected data at the existing cairn and found that it was 3.9 meters northwest of the zeropoint.
Total time off of Highway 167 was 0:45 with 5.8 km driving. My round trip hike was 526 meters and took me 19 minutes including about 10 minutes spent in the vicinity of the confluence.
Onward to 42N 115W!
