McWay Falls is an 80-foot-tall waterfall on the coast of Big Sur in central California that flows year-round from McWay Creek in Julia Pfeiffer Burns State Park, about 37 miles south of Carmel, into the Pacific Ocean. It is a tidefall, a waterfall that empties directly into the ocean, A relatively rare thing, there are only approximately 25 tidefalls found across the globe. There are only six in all of North America. McWay Falls, shown here, is one of two found in California, the other being Alamere Falls.
Antelope Canyon is a slot canyon in the American Southwest. It is on Navajo land east of Page, Arizona. Antelope Canyon was formed by erosion of Navajo Sandstone, primarily due to flash flooding and secondarily due to other sub-aerial processes. Rainwater, especially during monsoon season, runs into the extensive basin above the slot canyon sections, picking up speed and sand as it rushes into the narrow passageways. Over time the passageways eroded away, making the corridors deeper and smoothing hard edges in such a way as to form characteristic "flowing" shapes in the rock.
Rodeo Lagoon is a coastal lagoon located in the Marin Headlands division of the Golden Gate National Recreation Area, which is in southern Marin County, California.[2] This brackish water body is separated from the Pacific Ocean by a sand bar that forms Rodeo Beach. Rodeo Lagoon empties into the Pacific Ocean when the water level reaches a high enough level to erode through the sand bar. This high water level usually occurs in the winter months.
