Geologic map of science study area 2, north Kasei Valles, Mars (MTM 25072 Quadrangle)
This map is one in a series of 1:500,000-scale geologic maps initiated by the National Aeronautics and Space Administration to investigate areas of particular scientific interest on Mars. The north Kasei Valles area (fig. 1) merits detailed geologic study because it c ontains part of a large channel system whose age can be determined relative to geologic units that range in age from early intermediate (Early Hesperian) to the very late (Late Amazonian) periods of Martian history . Also, many geomorphic features in the map area suggest changes in water level and multiple erosional events associated with the Kasei Valles system. Later erosional events are indicative of spring sapping ; small-scale, ground-water runoff; and water-mobilized debris flow. Therefore, this large-scale mapping has increased our understanding of the history of hydrolo gic processes on Mars (Chapman and Scott, 1989). For these reasons, part of the area is a candidate site for a sample-return mission to the planet.
Geologic map of Bryce Canyon National Park and vicinity, southwestern Utah
Bryce Canyon National Park is located along the eastern escarpment of the Paunsaugunt Plateau, which along with the Markagunt Plateau to the west, form the southernmost of the High Plateaus of Utah. The park’s unique scenery has been created by forces of differential erosion acting on colorful rocks exposed along and below the rim of the plateau. Park headquarters and major scenic viewpoints that lie on or near the rim of the plateau are accessible from Utah Highway 12 mi west of the park. More remote parts of the park are located in canyons beneath the rim and are accessible only by foot, along horse trails or from a few unimproved dirt roads that approach the park boundary from the east or south.
