Hillhouse Hollow is a stream valley in northeastern Wright County in the Ozarks of southern Missouri.[1]
The source area for the intermittent stream in the valley is at 37°21′49″N 92°28′25″W / 37.36361°N 92.47361°W and the confluence with the Gasconade River is at 37°25′21″N 92°24′10″W / 37.42250°N 92.40278°W.[1] The stream source area is just east of Missouri Route Z and it flows northeast past the community of St. George and passing under Missouri Route H to its confluence with the Gasconade adjacent to Missouri Route T.[2]
Hillhouse Hollow (or Hill House Hollow) was so named due to the "hill houses" located above it in pioneer days.[3]
