The trail vanishes into a pond here. Circling along the edge, looking for the trail, branches slap at your faces and your gear (such as packs or protruding weapons) gets caught by vines. The pond appears to be at least 100ft across, but its edge is irregular and not easy to see. At the far edge, at what ought to be the pond’s exit is a beaver dam. The dam is woven of logs, sticks, and leaves, easily 6ft high above the stream at its center, 3ft at its edges. It is in excellent repair; some of the branches on it still have green leaves. The pond spreads out from there and one can see the top of a beaver lodge 20 yards out in the pond. The stream spills under the dam, filling a wide channel there. The pond covers the trail. The players have to pick a place to ford the stream, either above or below the dam. The trail continues once the pond is crossed or the river forded. Curiously, there is no beaver. Several small turtles, mostly a hand span across but sometimes larger or smaller, can be seen in the pond. Most are scrunched together on a log a dozen yards out in the center of the pond and around the beaver lodge. They bask in a strange posture in the occasional beam of sunlight, their heads and legs all sticking stiffly out from the shell. A giant turtle hides in the pond's edge. Anyone at the pond's edge for more than 3 rounds will likely be attacked. The turtle has tactical advantage on Dex (Stealth) checks while in the Pond. - MCMLXXV
