Good pictures. You are in better physical shape than I!

Hassayampa River - I reckon it depends on time of year, but I remember it, south of Wickenburg, as a river where water would disappear several times, then come back to surface. No good for canoeing!

That cactus on the lower right of picture six seems to be telling a guy something.

The ridge in picture 9 is the apex of a thrust fault. They go for miles, and are often associated with high temperature minerals.

I would like to know who piled the large rocks one on top. He big muscle guy.

Look for mineral across the road in picture 40. Bet you find some.

Lemme know.

COPPER BASIN - SIERRA PRIETA TO SKULL VALLEY SMALLER PLACERS

by Jane Boyles 1463

Access to the Copper Basin area is either up 89 north of Wilhoit to Forest Service road # 53 or from Prescott on Copper Basin Road. Placers in the Copper Basin district are found in gulches dissect the pediment on the southwest side of the Sierra Prieta to the area known as Skull Valley. A small amount of gold was recovered near Thumb Butte in the northeast slope of the mountain in the 1930’s. The gulches contain gravels with oxidized copper deposits and some gold placers. Other placers have been found in Mexican Gulch, Copper Creek and Spruce Canyon. The placers of the Copper Basin were worked intermittently until 1931. Parts of Copper Basin Wash carry water most of the year. The gold bearing gravels are made up largely of granitic sand with boulders and clay. Nearer the mountain the boulders are more prevalent. Gold is more abundant as one nears bedrock, which can be quite deep in places. There is abundant black sand in the upper portion of Copper Basin Wash. Throughout the southwestern part of the basin small particles of Cinnebar appear in the placer concentrates. The area around Gabarina Hill contains a lot of concentrated minerals. At one time Phelps Dodge had large holdings in the area.

MODEL PLACERS

The Model placers are located on the western side of Peeples Valley. Here there is a granite pediment extending from the eastern end of the Weaver Mountains to Peeples Valley. The
principal gold bearing gravels occur in an area with a width of about ¾ miles downstream on Model Creek from the old Pawley Place.

Again it is in a layer resting on the granite bedrock.

KIRKLAND PLACERS

The Kirkland Placers are located between the headwaters of Kirkland Creek on the northwest flank of Weaver Mountain and Kirkland. The placers were worked until 1957 but little is known about the production.

GRANITE CREEK PLACERS

Gold placers occur along the upper branches and main course of granite Creek, which rises a few miles south of and flows northward through Prescott. New England gulch, south of Prescott, was worked heavily and was a rich producer over a hundred years ago. It has been know to find gold in the excavation process for building in the town.

GROOM CREEK PLACERS

Along Groom creek about 4-6 miles south of Prescott is located several placers. The creek starts in the Bradshaws west of Walker and joins the Hassayampa at an elevation of about 1900 feet. Quartz veins located within the pre-Cambrian schist were the original source of the gold in these placers.

HASSAYAMPA PLACERS

Gold placers are located along the whole length of the Hassayampa in Yavapai County. The principal rock in the southern part of the county is pre-Cambrian granite and schist. The gold found along the upper reaches of the water drainage is
course and progressively gets finer downstream. The failure of the Walnut Creek dam in 1890 prevented the large scale operation planned for downstream. The river headwaters are at 7000 feet and cross into Maricopa County about two miles
north of Wickenburg. Due to its large drainage area it carries torrential floods, often moving the soil around with gusto turning up new ground for prospecting.
