Nisqually--Sequalitchew Historic District National Register of Historic Places Listing

History piles up thick here. Before the Americans arrived, the Hudson's Bay Company built Fort Nisqually right near the mouth of Sequalitchew Creek in 1833, making this muddy outpost the first European agricultural and trade hub on Puget Sound. They traded blankets and wool for beaver pelts with the local Nisqually tribe. Things got complicated fast. By 1841, US Navy Lieutenant Charles Wilkes showed up with his Exploring Expedition, planting an observatory brass marker in the dirt to claim a scientific stake for America. This quickly accelerated the region's transition from British fur-trapping territory to US soil, setting off decades of treaty disputes and cultural displacement.

Decades later, the ground shifted from beaver pelts to high explosives. In 1906, the DuPont Powder Company bought thousands of acres along the water to build a massive dynamite manufacturing plant, churning out millions of pounds of blasting powder that literally carved out the canals and railways of the expanding American West. They built a town too. It was a classic, self-contained company village, featuring neat rows of Craftsman-style houses for the workers. You can still find the old narrow-gauge railroad tracks where trains carted volatile nitroglycerin through the woods. A stark reminder of the dangerous, sweat-stained labor that built the modern Pacific Northwest.
