Esparto Quadrangle Ver. 2.0 Traditional Cache

The best parking for this cache is eastbound near the telephone pole just east of the cache location.

The cache is placed in the USGS Esparto Quadrangle in California. This is a replacement for our archived thirty-first cache in our series of caches placed near the site for which a USGS 7½-minute quadrangle map is named.

Esparto is a small community located in Yolo County, California.

The Quadrangle boundaries are:
N 38º 37’ 30” and N 38º 45’ 00”
W 122º 00’ 00” and W 122º 07’ 30”.


The United States Geological Survey (USGS) has many missions. At one time, a major mission of the USGS was the supplying of topographic maps of the United States on several scales. Our cache series is based on the 7½-minute quadrangle series.

The term quadrangle is used, instead of quadrilateral or rectangle, because the sides of these blocks are curved. The USGS divided the United States into quadrangles that are 7½ minutes by 7½ minutes. Since a degree is divided into 60 minutes, a quadrangle one degree by one degree contains 64 of these quadrangles.
