Our fall foray on September 23-24, 2023, took us to Salt Fork State Park in Guernsey County, in the unglaciated Allegheny Plateau region of southwest Ohio.

Salt Fork is the largest state park in Ohio, with more than 27,000 acres. The bedrock geology of the area includes sandstone, conglomerate, coal, shale, siltstone, and limestone.

One of our collecting sites on Saturday was Hosak’s Cave, a large shelter cave formed by the erosion of coal and shale underlying thick layers of more resistant sandstones and conglomerates. Another Saturday morning site was Stone House Loop Trail, which had a variety of mesic wooded habitats with numerous sandstone slump blocks. Saturday afternoon we collected at Morgans Knob, a mesic forest that includes a small pine plantation and an open meadow at the top of the knob.

Our microscope room for Saturday night, at the Best Western Hotel in Cambridge, was well attended and powered by a great abundance of the best local pizza.

Sunday morning we concluded our collecting at the Horse Camp, which is an open area with lichen-covered trees, and along the adjacent Blue Loop Bridle Trail, primarily a hilly mesic forest.

We identified 24 lichen species, 32 mosses, 7 liverworts and 1 hornwort. Of these, 9 lichens, 19 mosses, 6 liverworts and 1 hornwort are new records for Guernsey County.
