Coastal survey: Oregon beaches see more short-term erosion
12/09/2013 - Jonathan Allan, DOGAMI coastal geomorphologist, has co-authored a U.S. Geological Survey report assessing shoreline change along the Pacific Northwest coast from the late 1800s to present. The study found that while the majority of beaches are stable or slightly accreting (adding sand), many Oregon beaches have experienced an increase in erosion hazards in recent decades.

Oregon historical mining information available online
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.
