US-450511b

A postcard of Cystal Lake Cave on Highway 5 south of Dubuque, Iowa. It shows the spectacular geological formations of aragonite crystals, anthodites (cave flowers), stalactites and stalagmites inside the cave. Thanks motherbrando for another postcard sent with the same ID number.














Three stamps: a First-class (44 cents) independence bell stamp, a 10 cents American clock and a 44 cents Light tower of Sabine Pass, Louisiana stamp were used on this postcard. It was sent from Des Moines on 30.8.2009.
