The DESERT OF MAINE, covering 300 acres and surrounded by forests and green farmlands. This miniature Sahara, not unusual in coastal areas, is an example of the worst type of soil erosion.The first patch of sand, noticed in the latter part of the 19th century, was about 30 ft. sq. The sand stratum is present around the 300-acre (1937) area for a radius of six miles. In this circle a top layer of loam is either being covered or worn by frequent sandstorms. Some geologists believe the spot covers the bed of an ancient lake, perhaps formed by glacial deposits, for a glint of mica is apparent in the sand, which is very fine in texture. Sandstorms constantly raise and lower the desert level as the erosion creeps outward, the sand covering everything in its path, creating 30-ft. gullies and high dunes. The tops of trees once 70 ft. high appear as bushes, and strangely enough have survived the ages.
