 We're just now disembarking and getting on the way on the upper part of the Houston Ship Channel where the Bayou tributaries come together and where the channel was actually dredged from there, seven miles shy of downtown Houston to Galveston Bay. She tells me how the ship channel was built soon after the 1900 Galveston hurricane. It was the deadliest natural disaster in U.S. history and sent a warning to build trade further inland.
