blow-out
n.— «Many people don’t realise riding over dunes can do untold damage. “It damages the native vegetation and subsequently the dunes. Those pathways lead to what’s called “blow-outs”—producing a funnelling effect of wind from the beach. Even a small footpath can become more and more pronounced and results in the dune moving or retreating hundreds of metres in cases. Browns Beach is a good example. It has now lost two-thirds of the camping ground to the dunes just from fishers traipsing along a narrow path to the beach.”» —“Illegal fun” by Jenny Oldland, Kathryn Crisell Country Times (Kadina, South Australia) Nov. 7, 2006.
