Californians have seen a concerning image: a person standing next to a telephone pole with signs labeled with years, indicating the ground level for each year.
The signs on the pole read: "1962" at the top, "1970" several feet lower, and further down, "2015", followed by signs for "2019", "2021", and finally "2025" at the bottom.
Each sign represents how far the ground has sunk due to subsidence, showing the severe impact on the valley and the significant amount of water being pumped without replenishment.
The iconic photo illustrates the alarming rate of subsidence and its connection to groundwater depletion.
