- The vast hydraulic-mining pit whose 1884 lawsuit became America's first environmental ruling
- More
- Hydraulic monitors washed whole mountains through sluices here until Judge Sawyer's 1884 decision — the first major environmental ruling in U.S. history — shut the industry down. The bleached pit resembles a miniature Bryce Canyon; North Bloomfield's preserved town and the 1870s Humbug Day festivities complete it.
