I was on a hike and read a plaque that said this area used to be completely covered by water. My question is, where did all that water go? Just absorbed into the ground? Evaporated?

If all ice on Earth melted the global sea level would rise approximately 70 meters (approximately 230 feet).
That’s a lot of water. There have been periods in the past when the water level was much different compared to today.
Another thing is that geography changes over time. How high above the see level something is today doesn’t mean it wasn’t under water at some point.
