Apologies for yet another Kelly Mine smithsonite photo, but really, I'm not sure there can be too many.

Lewis & Clark in NebraskaNebraska, USA
The first explorer of Nebraska with some geological and mineralogical training was Meriwether Lewis in 1804, sent by President Thomas Jefferson, along with William Clark, to document the west and to search for a northwest (water) passage to the Pacific (“The Voyage of Discovery”). He had the second edition (1784) of Richard Kirwan's Elements of Mineralogy, which he tried to use, with little success, to identify minerals. Somewhere along the banks of the Missouri River in northeast Nebraska (between points 5 & 8 on the map), Lewis collected a number of selenite crystals ("a clear soft substance"), including at Calumet Bluff. These were sent from Fort Mandan to Charles Wilson Peale’s Museum in Philadelphia, at the direction of President Jefferson, then to Adam Seybert’s mineral collection, and finally to the Academy of Natural Sciences Philadelphia, where today seven of them are the only surviving mineral specimens from the expedition.

3VW-VK7Calcite (Var: Sand-Calcite) CaCO3Rattlesnake Butte, Jackson Co., South Dakota, USA
Dimensions: 13.1 cm x 8.9 cm x 6.8 cm
Weight: 513 g
Dramatic, large and sharp cluster of sand-calcite crystals from the classic Rattlesnake Butte locality on Oglala Lakota Sioux land. Ex Bob Jones, Ron Blackstone, Dana Slaughter. The Jones label gives the location as Washington County, which suggests it was collected prior to 1943.

Old Baldy from below, 2010Boyd Co., Nebraska, USA
Old Baldy, also known as the Tower, is a hill located near the village of Lynch. In this photo it is seen from the southeast. It is listed in the National Register of Historic Places because of its association with the Lewis and Clark Expedition. On their way up the Missouri River, on September 7, 1804, the two captains left the boats to explore the conspicuous bald hill, which they had seen from the river the day before. They climbed to the summit and measured its height as 70 feet. The hill is made up of chalky layers of the Cretaceous Pierre Shale, which do not support vegetation. Nearby, they discovered a colony of prairie dogs, an animal previously unknown to scientists, and spent the better part of a day capturing one alive, which they sent to President Jefferson. For its connection with Lewis and Clark, and because it has little changed since their passage in 1804, the site was listed in the National Register of Historic Places in 2004.

"Ionia Volcano" Historical MarkerNewcastle, Dixon Co., Nebraska, USA
Historical Marker in Newcastle for the "Ionia Volcano", a bluff along the Missouri River that is about 3 miles northeast of Newcastle (at 42.69068°, -96.83032°). Recent research has shown that the site was about a mile from the river at the time of Lewis & Clark's visit in 1804, and thus was not being undercut, and likely not the "burning bluffs" observed by them. However, there are other shale exposures along the west bank of the Missouri River in the area which were being undercut, and which may have been observed to be "on fire", either from oxidizing marcasite or pyrite or from burning lignite beds. Gypsum (or "selenite") crystals, resulting from the oxidation of iron sulfides, have been found at several locations along and near the river in northeast Nebraska. Several were collected by Capt. Lewis in 1804, and made their way into Adam Seybert's collection, and then to the Academy of Natural Sciences of Philadelphia, where they are apparently the only mineral specimens from the expedition still preserved .

XWD-U1CCalcite (Var: Sand-Calcite) CaCO3Mitchell, Scotts Bluff Co., Nebraska, USA
Field of View: 10 cm
Illustration of sand-calcite crystals from Barbour & Fisher (1902) American Journal of Science, XIV, p. 453. These crystals were found in the Oligocene Chadron Sands near the North Platte River in widely scattered areas west of Mitchell to the state line. They were fairly uniform in size (~40 mm.) and similar to the Rattlesnake Butte sand-calcites on the Pine Ridge Reservation in South Dakota, except with a different crystal form (a combination of acute and obtuse rhombohedrons), and found in a stratigraphically-lower formation.

RWV-RH2Pyrochlore Group A2Nb2(O,OH)6ZElk Creek Carbonatite, Elk Creek, Johnson Co., Nebraska, USA
Field of View: 200 μm
Cross-polarized light image of pyrochlore crystals in dolomite carbonatite. From a thin section of a core sample (depth = 1043 ft.). These crystals are about 10 microns across. They have been observed up to about 2 mm. across (in cores). Pyrochlore is the source of the high niobium concentrations in this deposit.
