Chronology
Deep-time dates are rounded as geologists give them. Prehistoric periods are given in radiocarbon years, the boundaries Chapter 3 follows. Where the record gives two dates for one event, both are shown. Within each part the entries run in date order, and the parts on timber and on mills, roads and visitors cover some of the same decades.
Deep time
- About 1.48 billion years ago. Eruptions of silica-rich magma build the Eminence caldera around the place where the Jacks Fork now meets the Current, and the ground collapses into a broad basin; these are the oldest rocks in the Jacks Fork country (Chapter 1).
- About 1.47 billion years ago. Lava cools at Shut-In Mountain near Rocky Falls, dated at 1,470.4 million years (Chapter 1).
- About 1.46 billion years ago. Granite near Big Spring cools underground, dated at 1,461.8 million years (Chapter 1).
- About 1.46 billion to a little over 500 million years ago. Long erosion wears the volcanic country down to buried hills, and more than 800 million years go missing from the record at the Great Unconformity, about 980 million at Rocky Creek (Chapter 1).
- A little over 500 million years ago. A warm, shallow sea floods the worn-down land near the equator, the volcanic knobs become islands, and the Lamotte, Bonneterre and Elvins layers begin to pile up around them (Chapter 1).
- About 501 to 485 million years ago. In the Late Cambrian sea the Potosi and Eminence dolomites form, and mats of microbes build stromatolite reefs (Chapter 1).
- About 485 to 470 million years ago. A shoreline moving back and forth across southern Missouri lays down the Gasconade Dolomite, the Roubidoux Formation and the Jefferson City and Cotter dolomites, the rock of the river’s bluffs and uplands (Chapter 1).
- About 470 million years ago. The youngest bedrock of the Jacks Fork country is laid down, and nothing survives from then until the loose gravel of the last few million years (Chapter 1).
- About 359 to 323 million years ago. In the Mississippian Period the sea returns at least once and leaves limestone, later eroded away except for loose blocks of chert on the uplands (Chapter 1).
- Roughly 300 million years ago. Mountain-building to the south and east squeezes the region, opening faults and joints, sending hot fluids through the rock that leave lead ore and turn limestone to dolomite, and raising the Ozark dome (Chapters 1 and 2).
- About 252 to 66 million years ago. Through the Mesozoic Era the Ozarks are dry land wearing down, and no rock of the dinosaurs’ age is preserved here (Chapter 1).
- About 66 million years ago to the present. Through the Cenozoic Era weathering and erosion go on, and the rivers cut their valleys, bluffs and hollows (Chapters 1 and 2).
- About 2.6 million years ago. The Pleistocene ice ages begin; the ice sheets stop near the Missouri River, and the cold reaches the Ozarks as frost-shattered slopes, blowing loess and northern plants (Chapters 1 and 2).
- About 12,500 to 9,300 years ago. The upper twenty feet of fill under a high terrace on the Current is laid down as the ice age ends (Chapters 2 and 3).
- About 12,000 years ago. The ice ages end, and by about 12,000 radiocarbon years ago a forest of oak and other hardwoods has replaced the spruce and pine of the Ozark plateau (Chapters 1 and 3).
First peoples
- More than 13,000 years ago. People begin to stop on the bench at Two Rivers, a seasonal camp they will use for more than 13,000 years (Chapter 3).
- About 9250 to 7500 B.C. In the Paleoindian period a few hunters leave fluted points in the valleys, among them a fluted fragment at Two Rivers, read as a Clovis point and, in 2016, as a Sedgwick point of Arkansas chert (Chapter 3).
- About 8950 to 7900 B.C. Dalton people camp at Alley Mill, Two Rivers and Akers, leaving serrated points, adzes and a buried base camp at Alley (Chapter 3).
- By about 8000 B.C. Ozark chert, as raw stone and as finished tools, is traveling to the lowlands to the southeast, and the valleys seem to be lived in without a break from about this time until perhaps 1300 (Chapter 3).
- About 7500 to 5000 B.C. Early Archaic people keep seasonal camps on the terraces (Chapter 3).
- From about 7000 B.C. The long warm, dry spell called the Hypsithermal pushes prairie east into Missouri, and in the Middle Archaic, about 5000 to 3000 B.C., people camp on the terraces near the water (Chapter 3).
- About 3000 to 600 B.C. In the Late Archaic sites grow more numerous, larger and denser, with stemmed dart points of chert, quartzite and rhyolite (Chapter 3).
- About 600 to 250 B.C. In the Early Woodland the first pottery, a few sand-tempered pieces, reaches the two rivers (Chapter 3).
- About 250 B.C. to A.D. 450. The Middle Woodland is known from a handful of sites, and stone cairns stand on the upper Current (Chapter 3).
- About A.D. 450 to 900. Late Woodland potters on the Jacks Fork and the upper Current temper their clay with crushed limestone, and the bow replaces the atlatl in the Midwest by about 750 (Chapter 3).
- Late in the 600s. Potters on the upland streams are probably tempering with shell, earlier than the great Mississippian centers, which take it up only after 1000 (Chapter 3).
- About A.D. 900 to 1200. In the Early Mississippian, people live in farmsteads and hamlets on the terraces and make shell-tempered pots and small arrow points (Chapter 3).
- Probably the 1000s. A wall-trench house stands and burns at the Shawnee Creek site, on a terrace of the lower river, the first such house found anywhere in the Current River region; a summary of its dates gives about A.D. 1025 to 1075 (Chapter 3).
- About 1250, or soon after 1300. The people of the upper and middle Current and the Jacks Fork leave the valleys, probably for the lowland towns to the southeast, and after 1300 the eastern Ozarks are largely empty (Chapter 3).
- 1500s and 1600s. Hunting parties, probably from the far southeast corner of Missouri, visit the empty valleys and leave a few arrow points and a broken fish-shaped bowl in a cave (Chapter 3).
- 1541. The Spanish expedition of Hernando de Soto reaches the central Mississippi valley, among Mississippian peoples who may be the cultural kin of the river’s last villagers (Chapter 3).
