This might look boring. Let me convince you otherwise.

The red/purple rock on the right is Triassic Chinle formation, a shale preserving flood plain and swamp from 200 million years ago.
On the left is tan bedding of the Pleistocene Santa Fe supergroup formation, formed from erosion along the slopes of the Rio Grande Rift Zone. These beds are around 200,000 years old at this location.
At this contact, there is a magnitude of 1000 times difference in geologic age. That’s how much rock is missing due to erosion and tectonics.
Way cool unconformity. Near Carthage, New Mexico.
