[10] In the early part of the 20th century, the alignment of U.S. Route 80 in Arizona passed in front of the property, increasing traffic and making it a tourist stop on the cross national highway, until the road bypassed the area.

John Ross Browne described his visit to the Agua Caliente Springs from Grinnel's Station in 1864: While the Company were encamped at Grinnell's, Poston, White, and myself crossed the Gila, and rode about six miles to the ranch of Martin and Woolsey, situated near the Aqua Calliente.

The water is of an exquisite temperature, and possesses some very remarkable qualities in softening the skin and soothing the nervous system.

Indeed it was not quite safe now; and I could not but think, as Poston, White, and myself sat bobbing about in the water, what an excellent mark we made for any prowling Tontos that might be in the vicinity.

The barren mountains in the rear, and the wild and desert appearance of the surrounding country, accorded well with the impressive narrative of that disaster.

A resort was built there in 1897 with 22 rooms and a swimming pool in which the hot waters from the spring collected for the use of the visitors.

The remains of the hotel has survived into the present but the hot springs dried up as ground water was pumped out for irrigation.
