Environment Research (Investigation Type)
These are studies that examine aspects of the present or past natural environment to provide a context, often off-site, for interpreting archaeological resources. Sometimes reported in stand-alone volumes representing significant research, such investigations may include geomorphological, paleontological, or palynological work.
626-650 (2,079 Records)
This study was carried out for US Army Alaska, Fort Richardson, in order to comply with Section 110 of the National Historic Preservation Act of 1966 (as amended). The purpose of this report was to establish the historic context of the Old Eklutna power plant. This is necessary so that Fort Richardson may identify and assess remains associated with the system that are found on its land.

EcoPLis--AdP: Human Occupations in the Pleistocene Ecotones of River Lis - Abrigo do Poço (WGF - Post PhD Research Grant) (2016)
This resource is an application for the Post PhD Research Grant from the Wenner-Gren Foundation. The coarse and dispersed information on the western-most Iberia does not allow a detailed understanding of the human behavior ecology and ecodynamics during the Pleistocene. That problem can only be solved with an innovative project focusing a region rich in multiple resources that is an ecotone between different landscapes and where can be found sites with long sequences and good preservation of...
Effective Hydration Temperature and Relative Humidity Variation within the Nevada Test and Training Range, Southern Nevada (2006)
Many obsidian artifacts are found at archaeological sites within the Nevada Test and Training Range (NTTR) and Nevada Test Site (NTS) because of the proximity of several geological sources of obsidian. These artifacts are datable using the obsidian hydration dating method, but effective hydration temperature (EHT) and relative humidity (rH) are significant extrinsic variables affecting hydration rates and, thus, age estimates of artifacts based on hydration rind thickness. Saline diffusion cells...

El Rio Bonito: An Ethnoecological Study of the Bonita Creek Watershed, Southeastern Arizona (1993)
The Bureau of Land Management is aware of the evidence for long-term human habitation along Bonita Creek. It has been said that, at times during the last century, Bonita Creek was home to perhaps dozens of families. Details of this period of occupation are, however, wanting. In addition, the town of Safford has been drawing substantial quantities of water from Bonita Creek for many years. How has this history of human use affected the environment of Bonita Creek? To answer this question, the...
Elemental composition of Kenya 2012 ochre sources (2012)
The results of each ablation performed on an ochre sample are presented in this table with elements in parts per million and oxides in percent weight, as measured by Homogenized Ochre Chip Laser Ablation-Inductively Coupled Plasma Mass Spectrometry (HOC LA-ICPMS). *Mean FeO as percent weight Fe2O3+FeO was determined by Electron Microprobe Analysis of each ochre chip and was used as an internal standard for LA-ICPMS data reduction. Elements labeled in red should be excluded from statistical...

Elizabeth Mine: Protecting People, Ecosystems, and Heritage - A Shared Legacy (2006)
The Elizabeth Mine Superfund site is an abandoned copper and copperas (ferrous sulfate) mine located in the Vermont Copper Belt in the east-central part of the state. The ore body was first discovered in the late 1700s and copperas production began soon after in the early 1800s. Mining activities continued at Elizabeth Mine for nearly 150 years. Over the years, historic tailing piles and waste piles have become a substantial source of acid mine drainage (AMD). The historic significance of the...
