(visited by Shawn Fleming)

31-Aug-2003 -- This would be a confluence filled Labor Day weekend. Nine successful attempts would be made making a large triangle across Nevada and partially into California with four confluences on each side. Proceeding east to 35n-115w, my plan was to proceed north to 38n-115w capturing four ( 35n-115w, 36n-115w, 37n-115w, 38n-115w), then due west to 38n-118w for three more ( 38n-116w, 38n-117w, 38n-118w), then diagonally southeast capturing the remaining two ( 37n-117w, 36n-116w), leaving a single confluence in the center which, at 37n-116w, will likely never be visited. Total round-trip mileage ended up being 1240 miles.

Just on the east side of Nevada 773 is where 38n-118w is located. Not much more than a 30 second walk from the road lies a rock cairn that our triply redundant Garmin system determined to be about 6 feet north of where we had located 38n-118w - based upon the GPS constellation geometry at this particular instance in time. Averaging and differential correction can reduce the position error but the point will still wander about. My kids had a lot of fun navigating to the intersection. I took the required pictures and then we all piled back in the RV for our next destination.

Total round-trip distance from highway 773 was about 300 feet and time was under 20 minutes. Two sides of our traingle were now complete, time to proceed southeast! Off to 37n-117w!
