In April 2001, I visited Big Bone Lick State Park in Kentucky. The heaps of mastodon and other large skeletons that used to loom out of the brackish backwaters along the Ohio River here are long gone, though the occasional big bone sometimes comes to light.

There's even an aircraft sensor system that sends down hundreds of thousands of pulses of light measured at different return rates. It allows you to literally strip away vegetation and see entire cities beneath the rain forest canopy. This is the unbelievable future of archaeology.
