Last September a new cache was placed about a mile from where I work. It is a small area, but the dominant features are boulders.. thousands of them totally covering an area of perhaps 30 acres. Some are the size of small cars, others are much smaller, but the ground is nearly covered by rock. I don't use a GPS and of course the USGS really smooths out the contour lines in places like this so it became a real search for me. The discription said "under a large boulder" so over the next few days, I got to know each of them by their shape and position. After about 3 unsuccessful trips I paced in to the spot that I thought was indicated on the map from three different landmarks on the USGS.. each of which was perhaps 200 meters away... and came to the same spot each time. Here I built a small cairn to save time later and came back several more times to search an area centered on the cairn. In November, with daylight savings time gone I was forced to put the search on hold, but a couple days ago someone put up a photo of them at the site. In the photo... a foot from the open cache was my cairn. Went there early the next morning and found the cache was beneath the same rock that I had chosen as the base of my cairn. So my map reading was perfect and my vision greatly flawed edscott
