A short walk from the trail head in Castle Rock is an interpretive shelter that explains the natural history of the forest ecosystem. This shelter was constructed in 1970 and its roof has outlived its useful life. The PCRF, with a generous grant from our Partner REI, has sponsored creation and installation of new interpretive panels in the shelter. Over the 40 years since it was constructed, the original shake roof suffered extensive deterioration. In spring of 2019 we funded the re-roofing of the shelter. The new roof is shown on the right above during a Parks Docent training.
