Lewis County in southwest Washington can truly be called the “mother of counties.” Half of the present-day Washington and of British Columbia were carved from its original borders. But the county’s location astride the Cowlitz Trail between the Columbia River and Puget Sound meant that communities with good water access would develop first. The construction of the transcontinental railroad in the 1870s and innovations in logging technology were the major spurs to settlement.
