March 2, 1974, Tuesday. Sunday, Today is a windy and gusty day. The air is grey and the air is full of dust. The wind maybe blowing 30 to 40 miles per hour. It's from the south east. Now I can see that much dust is blown about, and even the sand will move today. However there can be few days like today since the photos of the dunes show but little wind having a polishing. Everywhere in the dunes the ditches stand in a little defect almost a foot above the general level. Some of this is due to the rush holding material, but in the main it must be due to sheet-washing removing material of the dunes. If this is true the dunes must be losing material at the present time.
