#TopoTuesday: The geologic story of Arches National Park in Utah begins roughly 65 million years ago, when it was a dry seabed. Geologic forces & erosion have combined to turn fractured rock layers into arches. There are more natural arches here than any other place in the world.

#topotuesday: Land Reclamation
Land reclamation can mean one of two things: building artificial land OR repairing and restoring disturbed land. Whether it's building new land for resorts, reclaiming coastline, or building barriers against natural disasters, land reclamation is a fascinating process!
