| Description: | Eildon Hills, 1.5 km south of Melrose, Roxburgh. Lower Carboniferous intrusions of trachyte and felsite, viewed from the west-south-west. The igneous rocks form elevated ground due to their relative resistance to erosion. The Eildon Hills are an obvious landmark feature of the area and were recognized as such by the Romans, who called them Trimontium, from their triple peak. They also realized their military value and occupied the summit as a signal station. The Eildon Hills consist of an unusual composite laccolith of trachyte with distinctive high temperature minerals. Scotland was the site of considerable volcanic activity during the Devonian and Carboniferous periods and most of the more prominent hills in this part of the Borders consist of igneous intrusions. |
