Green Springs Mt.

Green Springs Mountain is a real, named summit in Jackson County, Oregon, along the Green Springs Highway (OR-66) corridor east of Ashland.[1] The DB lists agate, jasper, carnelian, and chalcedony here — a reasonable fit for the area's volcanic geology, since this part of southern Oregon sits within the Western Cascades' Little Butte volcanic sequence of andesite and basalt flows, the kind of host rock that produces exactly this suite of silica minerals. What's genuinely unclear is access: the Cascade-Siskiyou National Monument boundary runs along this same stretch of OR-66, and the DB's own record leaves the location type blank. This dossier flags that ambiguity rather than guessing.

Green Springs Mountain is accessed via the Green Springs Highway (OR-66), east of Ashland in Jackson County, near the Green Springs Inn / Cascade-Siskiyou National Monument area.

General-area inference only: if agate, jasper, or chalcedony occur here, they'd typically be found as float weathering out of volcanic outcrops or in road cuts, surface-collected rather than dug. Unconfirmed for this specific location, and access status needs to be confirmed first regardless.

This is the single biggest open question in this dossier: the Cascade-Siskiyou National Monument boundary runs along OR-66 in this exact area, and national monument status can restrict or ban collecting even where surrounding BLM land allows it. It is not confirmed whether this specific coordinate falls inside or outside the monument boundary. Before visiting, contact the BLM Medford District (541-618-2200), which administers both the monument and the surrounding public land, to confirm whether this exact location permits personal-use collecting.
