Since its founding in 1979, LaRamie Soils has completed more than 1400 projects for various clients. We have done work across the United States and internationally. Regions where we have completed projects include:

  • Powder River Basin (Wyoming, Montana, and South Dakota)
  • Big Horn Basin (Wyoming)
  • Souris-Des Lacs River Drainages (North Dakota)
  • San Francisco Bay (California)
  • San Juan Basin (New Mexico)
  • South Platte River (Colorado)
  • Arkansas River Basin (Colorado and Kansas)
  • Colorado Plateau (Colorado)
  • High Plains (Nebraska, Wyoming, Colorado, New Mexico, Texas, and Oklahoma)
  • Basin and Range (New Mexico, Nevada, Arizona, and California)
  • North Platte River Drainage (Wyoming)
  • Rocky Mountains (Wyoming and Colorado)
  • Lake Agassiz (North Dakota and Minnesota)
  • China
  • Pakistan

We are glad to provide a list of successful projects upon request, so please contact us. Below is a sampling of representative projects that we have completed over the years.

Reko Diq Geoarchaeological Reconnaissance

Location: Chagai District, West Pakistan

Year: 2010

This project examined soil formation processes in Pakistan and evaluated the relationship of humans to the land. In the American west a decrease in yearly precipitation equates with carbonate enrichment, where as in West Pakistan an increase in yearly precipitation results in the enrichment. In hyper arid landscapes like West Pakistan, landforms who owe their existence to water (e.g. alluvial fans and play lakes) are dominant. A primary geoarchaeological task is the examining of these formative events and how they influenced the cultural record. We recognized two such events associated with human occupation of the region. An equally important task is the understanding of human adaption and timing of comparatively arid climatic regimes. Our findings suggest an obvious human-land affinity for spring localities during relatively arid events which is enhanced during relatively mesic events along with playa and stream shore lines.

Studying shell midden in California

West Berkeley Shellmound Assessment

Location: San Francisco Bay Area, California

Year: 2001

One hundred twenty seven subsurface soil-sediment samples were collected (most beneath city streets) near an archaeological site. Sediments identified included: historic road metal, historic fills, Pleistocene and Holocene alluviums, and three faces of "bay mud." Soil-sediment relationships showed that the site occupied a peninsula and the banks of a small embayment north and east of the peninsula. We suggested that the elevation of the peninsula above the estuary influenced site location by providing protection from late Holocene sea level increases. Thirty eight of the core samples contained shell remains. Sediment-soil contexts indicated that seventeen of these were in situ. Seven sample localities below one area yielded shell remains associated with Holocene alluvium that represents an undated younger occupation whose relationship to the site is unclear.

Soil profile near the South Platte River in Colorado

Analysis of South Platte River Terraces

Location: South Platte River, Colorado

Year: 1994

This project involved a Class III geoarchaeological reconnaissance that was defined by a constant interval (50 m) subsurface sampling transect to identify locales within approximately 13 km of highway right-of-way with high potential to yield buried cultural materials. The work included an extensive backhoe trenching program at locales likely to hold cultural materials, examination and description of existing archaeological, paleontological, and Quaternary sites, and existing natural exposures including those in adjacent eolian terrains.
