A collection of drawings and paintings inspired by the geology and ecosystems of the Wissahickon Formation will be on display at the High Point Cafe at Allens Lane, 7210 Cresheim Road, Philadelphia, from January 5 – February 28, 2026. The works in this exhibition, which are from 2018-2025, are inspired by the Wissahickon Formation, a unit of bedrock that stretches through Southeastern Pennsylvania, New Jersey, and Delaware. It is composed of the metamorphic rocks schist, gneiss, and quartzite. To learn about rocks is to try to grasp the vastness of geologic (or “deep”) time. According to geologist and author Marcia Bjornerud, “Fathoming deep time is arguably geology’s single greatest contribution to humanity. Just as the microscope and telescope extended our vision into spatial realms once too minuscule or too immense for us to see, geology provides a lens through which we can witness time in a way that transcends the limits of our human experiences.” Many were created using egg tempera paint made with mineral, soil, and plant-based pigments, some of which started as components of the ecosystems that have sprung from the Wissahickon itself.

Please join me for an opening receiption on Saturday, January 17th from 3-5pm. High Point Cafe is open from 7am-5pm daily.
