Dos Lomitas Ranch

Dos Lomitas Ranch is a historic ranch property near the US-Mexico border within Organ Pipe Cactus National Monument. The buildings feature adobe brick construction with thick walls, wooden beam ceilings, and corrugated metal roofing, while packed earth composed the original flooring.

Robert Louis Gray built the main house in 1914 as the foundation of a cattle operation that eventually expanded to fifteen properties across the region. The ranch ran livestock from 1919 until 1976, when the Gray family ended their involvement following Robert Jr.'s death.

The structures display building methods adapted to desert living, with thick adobe walls and wooden beams that reflect how people constructed durable homes in an arid landscape. Visitors can see how local materials were chosen and arranged to withstand extreme heat and maintain cool interiors.

Visitors should wear sturdy shoes for dusty desert terrain and bring plenty of water, as the site sits in a remote location. The National Park Service offers on-site guidance and materials to help understand the property's history and layout.

The property retains its original packed earth flooring in several rooms, today offering a rare glimpse into early 1900s living methods. This flooring choice was practical for the time, helping to keep interiors cool during the hottest months.
