From Leadville to Canon City, the Arkansas River cuts through the heart of Colorado's mineral belt. It is famous for "Brown's Canyon" rafting, but the gravel bars hold significant gold.

The **Cache Creek** area (near Granite) is the premier public spot. However, large-scale mining damaged the river in the past.
Strict Rules: No motorized equipment. Sluices are allowed but must be fed by hand. Digging into the banks is prohibited. You must process material within the designated area.
A GPAA claim that is often open to the public (check current status). Excellent large gravel bars accessible when water levels drop in late summer.
BLM camping is plentiful (Hecla Junction, Ruby Mountain). Combine a rafting trip with a panning expedition.
The gold here travels far. It is very flat and high purity (90%+). It is excellent "jewelry gold" because of its brightness.
The best time to prospect the Arkansas is usually **August to October**. Spring runoff (May-June) makes the river dangerous and covers the pay streaks. Wait for the water to drop and work the newly exposed inside bends.
Strategic weight valuation. Calculate the spot yield of your discovery and bridge the target gap to a physical ounce.
"The gap to a full ounce is only 30.10 grams..."
