A weathervane on David Dale Owen�s final laboratory in New Harmony features a fossil fish and two invertebrate marine organisms: an Archimedes bryozoan and a blastoid. The David Dale Owen laboratory is an outstanding example of Gothic Revival architecture. Built in 1859, it features a slate roof, a returned boxed cornice, and an octagonal cupola with decorative brackets and a conical roof. It was built by David Dale Owen as a scientific lab, but was never used, as he died in 1860.

In 1836, he was appointed the State Geologist for Indiana (1837 to 1839), and in 1839 he was appointed U.S. Geologist by Congress. He led federal surveys from 1839 to 1840 and from 1847 to 1851 in the Middle West of the United States. In 1846, Owen proposed that the Smithsonian Institution be constructed of the distinctive red-brown colored Seneca Creek Sandstone. He also worked as State Geologist of Kentucky from 1854 to 1857; State Geologist of Arkansas from 1857 to 1859; and he returned as Indiana State Geologist from 1859 to 1860. His geologic studies focused on the economic importance of natural resources, such as ores and coal, to the westward expansion of the United States. David Dale used several buildings in New Harmony for his geologic studies. His first laboratory was Community House No. 1 used to store geological specimens, conduct experiments, and house the William Maclure mineral collection from 1826 to 1828. Soon thereafter, the Harmonist Shoe factory was remodeled and became the second geological laboratory for David Dale in New Harmony. Most notable is the use of the Harmonist Granary as his 3rd laboratory from 1843 to 1856, and the home of the precursor to the U.S. Geological Survey. His 4th geology laboratory is located next to the Granary, and is easily identified by its geologic themed weathervane modeled after three fossils: a blastoid, Archimedes (cork-screw shape), and a fossil fish.
