Figure 2 shows Google Earth imagery from 2015, with the position of dune slipfaces marked by light and dark blue curves along well-defined brinks and toes (light and dark blue, respectively). White and yellow curves mark the position of similar brinks and toes, respectively, in 1997.
Over the span of the 18 years, dunes changed shape and sinuosity while generally migrating downwind at about 3 meters per year.
Fig 2. Position of dune slipfaces, 1997 vs 2015, at Coral Pink State Park. White/yellow curves mark brink/toes in 1997; blue/navy curves mark brink/toes in 2015. Scale bars show 100 meters, and the distance that would be traversed over the 18 year period at migration rate of 5 m/yr, ie., 18 * 5 = 90 m. Source: Google Earth
