Geologic map of the St. Joe quadrangle, Searcy and Marion Counties, Arkansas Geologic map of the St. Joe quadrangle, Searcy and Marion Counties, Arkansas
This map summarizes the geology of the St. Joe 7.5-minute quadrangle in the Ozark Plateaus region of northern Arkansas. Geologically, the area lies on the southern flank of the Ozark dome, an uplift that exposes oldest rocks at its center in Missouri. Physiographically, the St. Joe quadrangle lies within the Springfield Plateau, a topographic surface generally held up by Mississippian...
Geologic Map of the Estes Park 30' x 60' Quadrangle, North-Central Colorado Geologic Map of the Estes Park 30' x 60' Quadrangle, North-Central Colorado
The rocks and landforms of the Estes Park 30 x 60 minute quadrangle display an exceptionally complete record of geologic history in the northern Front Range of Colorado. The Proterozoic basement rocks exposed in the core of the range preserve evidence of Paleoproterozoic marine sedimentation, volcanism, and regional soft-sediment deformation, followed by regional folding and gradational
Geologic Map of the Yukon-Koyukuk Basin, Alaska Geologic Map of the Yukon-Koyukuk Basin, Alaska
This map and accompanying digital files represent part of a systematic effort to release geologic data for the United States in a uniform manner. All the geologic data in this series will be published as parts of the U.S. Geological Survey Data Series. The geologic data in this series have been compiled from a wide variety of sources, ranging from state and regional geologic maps to...
Geologic Map of the Atlin Quadrangle, Southeastern Alaska Geologic Map of the Atlin Quadrangle, Southeastern Alaska
This map presents the results of U.S. Geological Survey (USGS) geologic bedrock mapping studies in the mostly glacier covered Atlin 1:250,000-scale quadrangle, northern southeastern Alaska. These studies are part of a long-term systematic effort by the USGS to provide bedrock geologic and mineral-resource information for all of southeastern Alaska, covering all of the Tongass National...
Status of Ground-Water Levels and Storage Volume in the Equus Beds Aquifer Near Wichita, Kansas, July 2008 Status of Ground-Water Levels and Storage Volume in the Equus Beds Aquifer Near Wichita, Kansas, July 2008
The Equus Beds aquifer in southwestern Harvey County and northwestern Sedgwick County was developed to supply water to the city of Wichita and for irrigation in south-central Kansas. Water-level and storage-volume decreases that began with the development of the aquifer in the 1940s reached record to near-record lows in January 1993. Since 1993, the aquifer has been experiencing higher...
Surficial Geologic Map of the Death Valley Junction 30' x 60' Quadrangle, California and Nevada Surficial Geologic Map of the Death Valley Junction 30' x 60' Quadrangle, California and Nevada
This surficial geologic map of the Death Valley Junction 30' x 60' quadrangle was compiled digitally at 1:100,000 scale. The map area covers the central part of Death Valley and adjacent mountain ranges - the Panamint Range on the west and the Funeral Mountains on the east - as well as areas east of Death Valley including some of the Amargosa Desert, the Spring Mountains and Pahrump...
