This diorama depicts the Alaska-Juneau Gold Mining Company (AJGMC) mill in Juneau, Alaska, on the Gastineau Channel. The diorama cost $3,500 in 1938 to construct and was animated with four motors totaling 840 watts of power. The painted backdrop showcases the mountains and distant buildings of downtown Juneau. In the left foreground is the bow of a large ship. To the right is a floating dock at which two smaller vessels are moored. A road comes down on the right side of the diorama, toward the viewer. A wooden mill building sits high on the right embankment.
The AJGMC mined low grade gold ore on the outcrop of the Juneau Gold Belt. The company's tunnels and mill site stretched to the Gastineau Channel, the waterway between the southeastern Alaska mainland and Douglas Island. The mine closed in 1944 due to the labor shortage brought about by World War II.
It is believed that more than one copy of this diorama was made with the initial one being done in 1938. The one for the Interior Museum was installed in 1945.
