An immense land as seen from the Top of the World Highway. We are nearly at cloud level, and just above the tree line which is about 2,500-3,000 feet elevation here due to the cold. 2013:08:19 08:52:34 Exposure time: 1/250 F-stop: 4.0 ISO speed: 1600 Focal length: 70mm

I did not dare to take any photos of the few and slight, scant buildings at the Canada-USA/Alaska border. We were there for 20-30 minutes and remained on the bus while our passports were collected, examined, but non-US citizens got off for routine questions to be admitted in person.

I shot these as we were lining up for the group photo of the "Grizzlies," our motor coach group, so I did not get everyone. The other group was the "Moose."

An independent gold mine, probably family run, with maybe a few non family member workers. There are quite a few operating in the region. They dig all summer while the ground is thawed out and sluice all winter.

Of all the Chicken locations in the world, you had to show up in mine. Chicken, Alaska, which claims a world exclusive on the name. I wonder why no one else uses it.

Rest stop in Chicken, Alaska. As I stepped off the bus behind Sharon, she asked, "I wonder if they take US dollars here?"
Say goodnight, Gracie.

Bucket boom to be lowered into the water and drag the buckets across the river bottom under the water and back up to the surface at the dredge end of the boom. The buckets are mounted to dig up from the bottom and carry the water and gravel up over the top of the boom. At this high point of bucket travel the gravel and water would fall into a trough to be directed to a series of sluices of decreasing grid size which would slosh out the water and lighter weight gravel and leave the gold. Some dredges would refine the gold with mercury and other means to purify it right on board, and others would ship the gold dusts to be so refined.

The whole thing would float while tethered by cables out the sides to poles into the bank. The dredge would rotate around a another single pole or "spud" driven into the river bottom so that the bucket line would operate in a circle around the spud covering the whole river bottom. The Tailings would go up a conveyor to be dumped behind the dredge (on the left here), making the "worm" pattern of gravel behind as this conveyor "tail" would turn around the spud also to exhaust the gravel out in the serpentine pattern. Creeks and whole river courses were altered for many miles by dredges.

Hydrological water spouts to blast the creek bank into gravel. A man would point the spout with a timber sticking out the back side as a lever arm. Woe be unto him if he lost his grip. At least one man died of a crushed chest when the thing spun around and hit him.

Two bucket lines, although they are just laying on the ground. I don't think they were attached to the chain linkage, but they were connected this closely to each other. Buckets ranged in size from 1.5 to 18 cubic feet, and these were about 15 or 18 cubic foot buckets. These are arranged in line upside down. Imagine them turned over and then dragged from the far end toward you up against the river bottom to raise gravel up to the surface and dump it into the structure to have the gold separated.

Closeup of buckets, and you can see the replaceable lips. Several are nearly new while many are worn.
