Event Details

The public is invited to a free special visit to the Porter House Museum’s unique and unusual Rock Wall on Saturday, July 20th. Visitors are welcome to arrive any time between 1 and 3PM.

As visitors explore the wall at their own pace, local educator Larry Berland will introduce visitors to some of the geological marvels in the wall. Regular museum staff will also be on hand to contribute historical information about the wall’s construction.

Before, during, and after the special event, the public is invited to “porch” at the museum—to enjoy the afternoon while seated on the historic Queen Anne porches and enjoying refreshments and lemonade.

Adelbert Field Porter (1879-1968) and his helpers built the wall over a six-year period in the early 1940s. The rough rocks, polished gemstones, and ancient fossils used in this unique wall were collected by Porter over a period of years during his travels in North and South America. The wall contains agates, jasper, onyx, amethyst, geodes, rose quartz, calcite, chalcedony, mica schist, sandstone, limestone, copper ore, iron ore, galena, petrified wood, and many others.

This event is the second of several free, special-topic tours in the new Summer Tour Series at the Porter House Museum. A free historic garden tour took place in June. An additional free, themed special tour will be held later this summer in August.
