The first railroad reached Virginia City. William Fairweather and other prospectors discovered rich placer gold deposits. The United States became a state. The first school in Montana opened.

Question 2

2. What is placer gold?

Gold locked deep inside coal layers. Loose pieces of gold mixed with sand and gravel in and along a creek. Gold that has been turned into coins. Only fool's gold made of iron.

Question 3

3. Which of the following is a method of placer mining?

Blasting tunnels with dynamite only. Melting entire hills with fire. Using pans, rocker boxes, or sluice boxes to wash gold from creek gravel. Planting trees and waiting for gold to grow.

Question 4

4. Why did miners in Alder Gulch start using hydraulic mining?

They wanted to use less water. The government forced them to stop using pans. Easy gold near the surface was running out, and hydraulic hoses could reach more gold in hillsides. It made the landscape look nicer.

Question 5

5. What was one major problem with hydraulic mining?

It did not move any dirt at all. It only worked in deserts. It caused serious environmental damage by washing away hillsides and filling streams with sediment. It made gold lighter than water.

Question 6

6. What is hard-rock (lode) mining?

Scooping loose sand from a creek. Digging tunnels and shafts into solid rock to follow gold veins and crushing the ore in stamp mills. Only using magnets to pull out gold. Letting the river move itself and picking up gold on the bank.

Question 7

7. What did dredge mining machines do in Alder Gulch?

Flew through the air to spot gold from above. Only cut down trees for lumber. Floated along the creek, scooping up gravel, washing it for gold, and dumping the leftover rocks in long piles called tailings. Turned all gold into paper money on board.

Question 8

8. What visible sign of dredge mining can you still see along Alder Gulch today?

Skyscrapers built by miners. Perfectly flat, untouched fields. Long rows of rocky tailings and ponds left where dredges worked. Large forests of palm trees.

Question 9

9. Why did most gold mining in places like Alder Gulch stop during World War II?

All the gold disappeared overnight. Miners decided they did not like gold anymore. A government order (L-208) said gold mining was "non-essential" so workers and supplies could go to war needs. The rivers froze forever.

Question 10

10. How do geologists today explain why Alder Gulch had so much placer gold?

Gold fell from the sky during one storm. People secretly buried gold there in the 1900s. Gold from older hard-rock veins eroded over millions of years and washed into the valley, concentrating in stream bends and layers. The creek water turned into pure gold at night.
