pfeifferfoundationMatilda and Karl Pfeiffer. Museum and Study Center. The Tulip Poplar leaf and seed pod were chosen as the logo for the Matilda and Karl Pfeiffer Museum and Study Center because of the unique connection of the tree to Crowley's Ridge. Crowley's Ridge is the only place in Arkansas where the Tulip Poplar grows naturally. It can be found along the ridge from the northern border of Clay County near Piggott to Helena in Phillips County.
