Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83).The geographic extent of the DOQ is equivalent to a quarter-quad plus The overedge ranges a minimum of 50 meters to a maximum of 300 meters beyond the extremes of the primary and secondary corner points. The overedge is included to facilitate tonal matching for mosaicking and for the placement of the NAD83 and secondary datum corner ticks. The normal orientation...

Slide description and index card: Aerial photographs of the lava dome that extruded into the crater of Mount St. Helens during the latter part of June 1980.The volcano's dacite lava has a pasty consistency when it is molten, and it tends to pile up rather than to flow laterally. This dome, which was largely destroyed in a subsequent eruption on July 22, 1980, was, at this stage, about 1,200 feet across and 200 feet high. Its rough, shattered appearance resulted mainly from the expansion and shattering of the solidified outer crust as more molten lava was forced upward by the great pressure in the magma chamber underlying the volcano. B, View from the west over the crater rim from a helicopter taking geologists to...
