Wikipedia's title for this place is Terwilliger Hot Springs; the record calls it Cougar Reservoir Hot Springs, and Cougar Hot Springs is a third name. It is a set of geothermal pools within the Willamette National Forest, Lane County, Oregon, about 26 miles from Oakridge and, by Wikipedia's count, 53 miles east of Eugene. The water runs hot, at the upper edge of a comfortable soak. Open to the public on Forest Service ground.

Location

The pools drain into Rider Creek, which feeds Cougar Reservoir. Aufderheide Drive, also known as Forest Service Road 19, is close. The record measures the spring at under a hundred feet from the road, while Wikipedia says about a quarter mile, so expect some walking. Low elevation, wet, with substantial winter snow. Slide Creek campground is under a mile away.

Winter, December through February, is when the record says to come. It is hot enough that you should ease in and get out if you feel light-headed. Camping at Slide Creek is very close. The record carries no fee, though check current Forest Service notices.

History of Cougar Reservoir Hot Springs

The Terwilliger name comes from Wikipedia's entry, which also lists Cougar Hot Springs. The record's own name ties it to the reservoir it drains toward. The USGS keeps it in its thermal inventory.
