The newborn park covered 400 square miles[1] at the junction of the Green and Colorado Rivers in Utah. It included such magnificent features as Island in the Sky, The Needles, Upheaval Dome, and the two great stone formations, Angel Arch and Druid Arch. On November 16, 1971, President Richard M. Nixon signed an act of Congress enlarging the park by 125 square miles in four separate parcels of land, so the area now totals 525 square miles, all in southeastern Utah, as shown on the map (fig. 1). The northern boundary was extended to include parts of Taylor and Shafer Canyons. The addition at the southeast corner takes in the headwaters of Salt and Lavender Canyons and part of Davis’ Canyon. The largest addition, at the southwest corner, includes grotesquely carved areas bearing such colorful names as The Maze, Land of Standing Rocks, The Fins, The Doll House (fig. 36), and Ernies Country (named after Ernie Larson, an early-day sheepman). The fourth parcel lies about 8 miles west of the northwest corner and encompasses much of Horseshoe Canyon, whose walls are adorned by striking pictographs (fig. 2). At this writing (1973) the park is still in its infancy, with most of the planned developments and improvements awaiting time and money, but a good start has been made. In 1960 my family and I first traversed Island in the Sky to Grand View Point over a rough jeep trail; now it is reached with ease over a good graded road which eventually will be paved. A temporary trailer-housed entrance station near The Neck will be replaced by permanent headquarters for the Island in the Sky district after water is piped up from wells drilled near the mouth of Taylor Canyon.
