DETAILS
* PLEASE NOTE AMENDED START TIME OF 1 PM *
Leader: Ian Francis
An afternoon excursion to Eycott Hill nature reserve to examine rocks and geomorphology at the site location of the Eycott Volcanic Group, a mid-Ordovician (Caradoc) sequence of basaltic andesite and andesite lava flows and sills, including an unusual porphyritic andesite lithology exposed near the base of the sequence. If time permits we will also visit Fairy Knott, north of Naddle Crag, where faulting reveals an exposure of the underlying Skiddaw Group.
The excursion will be held jointly with the Cumbria Wildlife Trust
