Description: The subset of glacier polygons on Hood, Jefferson, the Three Sisters, and Broken Top mountains. Removed all other features such as anything not in Oregon and snowfields (except Palmer). Also made minor changes of known errors, such as joining the Ladd Glacier feature (on Hood) with an unnamed "snowfield" higher on the mountain that is actually part of the Ladd Glacier. These changes were made at the direction of OGI. Reprojected.Important fields:GLACNAME: Name of the glacier or snowfield. May be blank/NULL.STATE: Abbreviation for the state in which the feature is found.QUADNAME: USGS quad (7.5minute?) in which the feature is found or was traced from.GLACNUM: Presumably an ID number for the glacier. It is unknown if the ID is used outside of this dataset.Polygon geodatabase format. Appropriate for 1:24,000 scale.PROJCRS / VERTCRS: EPSG:6556 / none
