Dunebergs Calving Into the Surf

South Padre Island, 11 miles beyond end of pavement, non-storm conditions, erosion from sea level rise, October 2017.  The dunes in the middle left distance are actively calving dunebergs into the surf. Tides are like the weather, some are more extreme than others because of winds, tides and other things. June 2018 to May 2019 saw 53 extreme high tides that eroded into the dunes. Normal is zero times per year. The dunebergs show a peculiar angle on the dunes where their feet eroded away and large blocks of sand slide down into the surf. A duneberg can be seen calving in the middle left of the photo.
