North Lonsdale Speleological Group
On July 3rd, a joint meeting of the Red Rose Cave and Pothole Club and the North Lonsdale Speleological Club, pushed an extension of the "Borehole" in Easegill from a previously known length of thirty feet to an approximately estimated one thousand, three hundred feet.
The extension, first entered at Easter this year by a member of the North Lonsdale, P. Mottershead ends in a passage above an unsafe boulder choke, believed to be in the region of the Depot in Easegill Caverns.
The new section, beyond the entrance, proceed as follows:
A ten foot pitch is followed for several hundred feet by a twisting stream passage five to six feet high, with thigh deep water: two bedding planes containing many formations including pillars, helictites, much calcite fluting and multitudes of straws, follow leading into a tight eight to ten foot high winding stream passage. This passage, dry at the time of exploration but apparently liable to complete flooding at times, corkscrews violently until reaching a fifty foot pitch (climb through rift in roof of passage about twenty feet before pitch and belay ladders and lifeline to large boulders near the head of the pitch. BEWARE OF LOOSE BOULDERS). Frome here a tight four foot high passage runs for a few hundred yards down to an unsafe ruckle of boulders. A "human pyramid" found a bedding plane crawl leading off above this choke, whilst another passage is believed to lead off at floor level.
The present end of the cave seems to be in the region of "Depot" and should a connection be proved, the Borehole will provide an easier means of access to the Lancaster Easegilll system.
