Fort Roberdeau is a park for people with many interests, not just the history of the fort itself. However there is a special symbiosis that occurs when the fort‘s history can be put into a new perspective because of those interests.
Pen Ambler is one of those special volunteers who has brought his interests to the Park, and has been able to help bring the area’s history to life in the process.
Pen is an amateur mineralogist, and for 47 years has actively collected and studied minerals, fossils and rocks. Pen founded the Blair Rock and Mineral Club in 1968. Early in the 1970’s, he became a member of Friends of Mineralogy – PA Chapter; has been a long-time member,, and is now vice president of the PA Chapter. His interest was sparked when he was a young man working with a highway surveying crew. After instruction, he was sent to Beaver County as an inspector to a core-boring outfit from W VA. Pen was impressed with the colors of minerals from the wet core borings resulting from drilling. Inspired he went to Carnegie Museum in Pittsburgh to learn and discover what else was underground that he didn’t know about.
