Dublin Gulch
"Dublin Gulch" is the name given to a unique collection of several dwellings carved into the banks of an ancient caliche deposit, believed to have been left by the Lava Creek eruption at Yellowstone over 600,000 years ago. During the 1920s, prospectors excavated these dwellings to take advantage of the natural insulation (and lack of rent) they provided. The name Dublin Gulch is believed to have come from German immigrant Joe Vollmer, who previously lived in an area with the same name in Montana.
While some of the dwellings were simple, others were more extensive and had ornate doors, decorative features, and even a garage. They remained in use for decades, with the last resident leaving in the 1970s.
