In Geology ✔️ Mineralogy - Botany #StreamCapture #Geomorphology #PigeonRiver #HominyCreek 🚨 Breaking: "Current News in Geology" 🔁 Imminent Stream Capture: Hominy Creek Poised to Seize Pigeon River's Headwaters ▶️ In the heart of the Appalachians, a geological drama unfolds where Hominy Creek threatens to capture the Pigeon River’s headwaters, potentially reshaping the region’s river systems in a rare geomorphological event. Formation Story The Pigeon River originates in the Blue Ridge Mountains of western North Carolina, near Sam Knob on Black Mountain at approximately 6,130 feet elevation. It flows north through Haywood County, past Canton, and into Tennessee, covering roughly 70 miles before merging with the French Broad River near Newport, Tennessee. Hominy Creek, a tributary of the French Broad River, begins nearby in the same rugged terrain. Both rivers are part of the Tennessee River system, shaped by millions of years of tectonic activity, uplift, and erosion in the ancient Appalachian landscape. The Pigeon River’s name traces back to the extinct passenger pigeon, whose migration once followed its valley. Geological Information Geologists have identified a fascinating scenario near Canton, North Carolina, where the headwaters of Hominy Creek lie just 1,500 feet from the Pigeon River, separated by a subtle drainage divide only 20 feet higher than the Pigeon’s banks. The Pigeon River valley sits “perched” approximately 400 feet higher than the adjacent Hominy Creek/French Broad valley, creating conditions ripe for stream capture. This phenomenon occurs when a lower-elevation stream erodes headward, intercepting the flow of a higher-elevation stream. The proximity is driven by a weak zone in the bedrock, likely a fault or heavily fractured rock, that both streams exploit, making erosion easier. Hominy Creek’s gorge follows a straight path along this weak zone, visible in its linear morphology and utilized by Interstate 40. While the capture is geologically “imminent,” it may still take thousands of years due to the slow pace of erosion. When it occurs the Pigeon’s flow could be diverted into the French Broad system via Hominy Creek, creating dramatic rapids and a deeper gorge due to the 400-foot elevation drop. This event is not attributed to differing climatic or uplift histories, as both rivers share similar conditions within the Tennessee River system, but rather to the local topography and bedrock vulnerabilities. ▶️ Interesting Fact The subtle drainage divide between Hominy Creek and the Pigeon River is so low that it’s nearly imperceptible, located near the Evergreen Packaging paper mill in Canton. A canal could feasibly link the two rivers today, hinting at how close this natural diversion is to happening. 🔎 What do you think the landscape will look like if Hominy Creek captures the Pigeon River? 🔁 Like & Share your thoughts on how this geological shift could impact the environment or local communities!

Trying to #getsmarter about #streamcapture. Super cool stuff, may have found an example in low relief terrain in #PolkCounty using submeter #QL1 #lidar @AGU_EPSP

Thinking about #StreamCapture lately and some of the oddities that NC's #SouthernAppalachian fracture controlled fluvial networks bring to light. Example for today - #Nantahala gorge. @AGU_EPSP Phil Prince's excellent piece: https://t.co/DmlxLjlzR0

Another excellent article about the Ä’äy Chù stream capture event of 2016, glacier science, climate change, and the Kluane First Nation perspective on large-scale changes to their traditional territory. #Streamcapture #kluaneglaciers #climatechange https://t.co/HOXUDEZ1RI

In 2016 the Ä’äy Chù in Kluane NPR suddenly disappeared. Scientists doing research in the park would come to discover the first documented case of river piracy, caused by the receding Kaskawulsh Glacier. #Streamcapture #kluaneglaciers #climatechange https://t.co/mul55Jf0L7

#StreamCapture cut out midway through the lecture so I'm going to have to repeat the recording of #ELEC270 lecture 2. It'll be up soon.

Wow one of this week’s #StreamCapture lectures has over 1000 “views” already. That was either really interesting…. or totally #incoherent 😳

Another victory for #StreamCapture. This term it’s StreamCap 3 v RBJ 2. Mic battery flat b/c charged by PC. Which is off unless In use 🙄

Two more rooms equipped with lecture capture yesterday. That's a current total of 110 across campus #streamcapture https://t.co/CHtgeWvtUx
