Description

Rich specimen with at least 7 different minerals: orange-brown tabular bassetite on straw-colored acicular strunzite (type loc.), red-brown bermanite, honey-brown tabular pseudolaueite (type loc.), red-brown robertsite and pale green botryoidal mitridatite on black rockbridgeite. Besides the obvious strunzite, rockbridgeite and mitridatite it's my visual ID and I might be wrong about the one or other species. Still it's 7 and a pretty interesting, asking for further investigation.
