Nachtrieb-Kelly Ranch

The Nachtrieb-Kelly Ranch, also known as Maxwell Ranch, near Buena Vista, Colorado, was listed on the National Register of Historic Places in 2017.

It is a historic cattle and hay ranch with 24 identified resources, including three pioneer log buildings. It is located 3.2 mi south-southwest of Buena Vista.

A 160 acre property on Maxwell Creek was homesteaded by Charles Nachtrieb in 1876. It was expanded to 640 acre by the early 1900s, and remained in the Nachtrieb family until 1936. The ranch has held grazing rights to a large area of adjacent public lands. After two other owners, it was acquired by the Kelly family in 1951, and a portion was eventually sold off, and the Kelly family continued to operate it in 2017.
