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...

Geologic map of science study area 1B, west Mangala Valles region of Mars Geologic map of science study area 1B, west Mangala Valles region of Mars

This map is one in a series of 1:500,000-scale geologic maps initiated by the National Aeronautic and Space Administration to investigate areas of particular scientific interest on Mars. The west Mangala Valles area merits detailed geologic study because it contains several small channels whose ages can be determined relative to geologic units that range in age from early (Noachian) to...

Geologic map of science study area 2, north Kasei Valles, Mars (MTM 25072 Quadrangle) 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 contains part of a large channel system whose age can be determined relative to geologic units that range in age from early
