In brief....

Oregon historical mining information available online
small image of MILO point locations in Oregon

Historical mine and commodities records, formerly available to the public at DOGAMI Portland and Grants Pass office reference libraries, are now available as PDF files in the Oregon Historical Mining Information (OHMI) archive. The first part of this ongoing project includes small-dimension maps, letters, news clippings, photographs, and reports. The agency plans to combine OHMI records with the GIS-based Mineral Information Layer for Oregon (MILO).

MILO-2 is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines. A subset of the data is shown on the interactive map; order the full data set from nature of the Northwest.

Reedsport wave energy study available

12/2/11 - DOGAMI Open-File Report O-11-17, "Baseline Observations and Modeling for the Reedsport Wave Energy Site, Douglas County, Oregon: Monitoring Beach and Shoreline Morphodynamics," by Jonathan C. Allan, Roger Hart, and Laura L. Stimely describes and summarizes baseline observations from monitoring the response of the beach and shorelines along approximately 16 km of the north Umpqua Spit shoreline adjacent to the proposed Ocean Power Technology (OPT) Reedsport wave energy site.

$2M grant could make early earthquake warning a reality in the Northwest
