## About Dunn Spring

Dunn Spring lies inside Harney County's Malheur National Wildlife Refuge, about twenty miles from Hines. It is a warm spring in name only; the water is barely warm, at the low end of tepid. The refuge restricts access here. For most readers this is a place on a map with a USGS site number attached.

There is no road close by. The nearest one is a bit over a mile off, with no name given for it, so getting there means a hike across refuge land. Fish and Wildlife manages the ground. The basin floor here is around forty-one hundred feet, where winter drops roughly two feet of snow and dry months follow.

Winter tops the list on the record. But the restriction on access matters more than season. Ask the refuge before you go, and expect a no. Camping is not listed anywhere close, and the water is too cool to matter anyway. Nobody has photographed it for the record.
