Etymology: An Ait or Eyot is an island in a river, most common in the Thames and tributaries.
The Ait
Most of the exposed rocks in the country are sedimentary and of considerable age; they are formed as a result of erosion processes caused by rain, ice, or rivers breaking up existing rocks and depositing the material so produced elsewhere. Over time this sediment is compressed to form sedimentary rocks. This process is taking place all the time and the Ait in Brabyns Park has only been formed over the last 40-50 years, by erosion of the existing Upper Carboniferous Rocks. In a few million years this Ait could itself be sedimentary rock, unless it is washed away by flood waters!

Material eroded upstream by the River Goyt is deposited in several ways and places depending on how much water is flowing in the river at any time, and by existing features whether natural or man made. Usually material is eroded/scoured from the outside of a bend and is deposited on the inside of a bend thus forming a beach. Material for the Ait could be of local origin i.e. either the east side of the park or directly opposite the beach.

To log this geocache:-
1. Give in centimetres or chains the average pebble size on the Ait or the beach
2. Give the height above the beach of the Park.
3. Estimate the age of the rock fragments which constitute the Ait and the beach.
4. Are the pebbles on the beach angular or smooth and what does that say about their origin?
