Cauldron Linn, or Caldron Linn, is a waterfall on the River Devon on the border between Clackmannanshire and Perth and Kinross in Scotland.
Caldron Linn is about a mile below Rumbling Bridge, and can be accessed through fields by Powmill, with a 150 ft slippery descent to reach it. The height of its fall was lessened in 1886 by rock fall. Here are two cataracts, distant from each other 28 yards. The upper fall, thirty-four feet in height, declines a little from the perpendicular; the rocks rise out of the channel, and there is one like a pillar, horizontal at the top, by which many persons have passed from one side to the other. Between these falls, the river has formed three round cavities, having the appearance of large caldrons or boilers. In the first, the water is perpetually agitated as if it were boiling; in the second, it is covered with a constant foam ; in the third, which is the largest, being 22 feet in diameter, it appears as if spread out in a large cooler.
These cavities are separated from each other by ledges of rock; they communicate, not by the water running over their brim, but by apertures about middle depth in their ledges, wrought out in the course of ages by the action of the water. The lower caldron discharges the water into the last fall through a similar aperture, having the appearance of a door or large window hewn out of the rock. Through this opening, the river...
