The Claims

Big Beaver Creek
& Little Beaver Creek.

Two placer claims, twenty acres each, tucked into Boise County eighteen miles past Idaho City — the town that exploded from a mudhole to twelve thousand people in eight months during the 1862 gold rush, then quietly returned to the mountain.

We're not just working the ground. We're building the intelligence layer that should have existed the whole time — mapping every bend, every bedrock crack, every place water has ever concentrated color.

Two Active Claims

BLM MINERAL RIGHTSACTIVE PLACER40 ACRES

Big Beaver Creek (IDC-BB-4471) and Little Beaver Creek (IDC-LB-4472). Two drainages, one mountain, two decades of accumulated placer deposits waiting for a systematic season.

Terrain Note
Channels largely stabilized since late-20th century reclamation. Creek beds show remnant hydraulic mining debris from the 1880s–1900s. Bedrock channels beneath current alluvial fill remain unmapped.
Gold Note
Active placer gold in both drainages, concentrated in bedrock crevices, behind boulders, and in natural trap pockets. Deeper buried channels may hold significantly higher concentrations.

GOLD RUSH ERA
1890

The Hydraulic Era

BOISE BASIN RUSHHYDRAULIC MININGCHANNEL DISTURBANCE

Twenty-eight years after the 1862 Boise Basin gold rush, hydraulic operations had dramatically altered Beaver Creek's natural channels.

Terrain Note
Hydraulic monitors used high-pressure water to blast hillsides, flushing gold-bearing gravels through sluice boxes. Creek channels were widened significantly. The Boise Basin produced an estimated $250M in gold (1860s dollars).
Gold Note
Easily accessible surface gold largely removed 1862–1880. Deeper bedrock channels and buried paleobeds untouched. The 1890 survey noted Beaver Creek as "worked but not exhausted."
BIG BEAVER LITTLE BEAVER N ↑
PRE-CONTACT ERA
1790

Shoshone Territory

NORTHERN SHOSHONENATURAL DRAINAGEPRISTINE CHANNELS

Seventy years before the gold rush, the Boise Basin was Northern Shoshone seasonal territory. The creeks ran in their natural state — wider, more sinuous, significantly more productive.

Terrain Note
Natural creek channels, free of mining disturbance. Beaver populations maintained natural dams, creating wetland complexes acting as gold-trapping sediment basins.
Gold Note
Centuries of undisturbed spring floods had redistributed placer gold into rich natural traps. This is the deposit that would cause the 1862 rush.
BIG BEAVER LITTLE BEAVER N ↑
LITTLE ICE AGE
1650

Peak Snowpack Era

LITTLE ICE AGEACTIVE REDISTRIBUTIONSHOSHONEAN PEOPLES

The Little Ice Age brought significantly deeper snowpacks to the Boise Mountains. Spring flooding was more dramatic, actively redistributing placer gold into natural trap zones.

Terrain Note
Ice age cooling meant 30–50% deeper snowpack. Spring flood events were larger, faster, and more energetic — cutting more aggressively into the valley floor and redistributing gold-bearing gravels.
Gold Note
The high-energy flood events of this era were key gold-concentration events. Placer gold sorted and concentrated in natural hydraulic trap zones — the same pockets later miners would find first.

ANCESTRAL ERA
1400

Ancestral Drainage

MEDIEVAL WARM PERIOD ENDSHOSHONEAN ANCESTORSANCIENT CHANNEL

At the close of the Medieval Warm Period, Beaver Creek ran older, slower, more braided. The original source gold — from Cretaceous quartz veins in the Idaho Batholith — had been eroding in for 65 million years.

Terrain Note
The creek channel in 1400 likely ran further east before Little Ice Age floods shifted it. Ancient meander scars visible in modern aerial photography as faint arcs of different vegetation.
Gold Note
65 million years of erosion from Cretaceous quartz veins in the Idaho Batholith. A mature, well-developed placer system waiting for Little Ice Age concentration events to set the stage for 1862.
