National Park Service Sound Spectrograms

National Park Service scientists record and analyze sounds in national parks to inform and improve management of national parks across the country. The data is collected through recording systems installed by the Natural Sounds and Night Skies Division in selected parks for about a month at a time. The systems record audio as mp3 files and sound pressure levels in decibels, and are designed to replicate the hearing experience of a person on the ground.

Views of Lehman Cave

Lehman Caves, large, spectacular cavern at Great Basin National Park in eastern Nevada, U.S. The cave lies 5 miles (8 km) west of Baker at the base of the eastern slope of Wheeler Peak (13,063 feet [3,982 meters]) in the Snake Range. It is made of light gray and white limestone that is honeycombed by tunnels and galleries containing a spectacular array of stalactites, stalagmites, and other cave deposits. The cavern was discovered in the mid 1880s by Absalom Lehman, a local prospector and rancher.

Map of Great Basin National Heritage Area

The Great Basin National Heritage Area was designated by Congress in 2006 to recognize its “classic western landscape that contains long natural vistas, isolated high desert valleys, mountain ranges, ranches, mines, historic railroads, archaeological sites and tribal communities.” The recognized Area is made up of two neighboring counties, White Pine in Nevada and Millard in Utah, as representative of the larger geographic Great Basin. The Great Basin National Heritage Partnership was designated at the local coordinating entity for the Area.

News from the Plains Arrival from the Salt Lake—News from the California Emigrants—Their Progress—Territorial Progress in the Great Basin


The Frontier Guardian reports that the crops in Utah are good and the crickets have almost entirely disappeared this season. Mormon relations with the California emigrants are good—many have been baptized and are staying in Salt Lake City. Utahans are celebrating the 24th of July this year instead of the Fourth for two reasons: the crops are not ready by the Fourth and the 24th is the day the first pioneers came into the valley.
