Mining History: Hydraulic Mining
The Malakoff Diggins is the largest hydraulic mining site in California. Years of hydraulic mining has left an artificial canyon 7,000 feet long, 3,000 feet wide, and 600 feet deep. Early, small scale placer miners referred to the area as Humbug due to many failed attempts to mine the local rivers. Yet, gold was there.

Plant hydraulics play a critical role in Earth system fluxes
Thus, plant hydraulics mechanistically links soil and atmospheric water stress to leaf gas exchange and also provides a clear and internally-consistent evolutionary optimization – plants are expected to maximize fitness by maximizing the benefits of carbon uptake minus the risks of hydraulic damage (Wolf et al., 2016; Sperry et al., 2017).
