Black walnut wood is highly prized for its dark-colored, straight grained, true heartwood and is among the most durable hardwoods in the U.S. The nutmeats provide a distinctive natural flavor and crunch as a food ingredient.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">This Tree\u2019s History<\/h3>\n\n\n\n<p>This heritage tree is located in Frenchman\u2019s Bar Regional Park, a 120-acre Clark County park dedicated in 1997. \u201cFrenchman\u2019s Bar\u201d was named after Paul Haury, a Frenchman who bound out to engage in fur trading in Alaska. Fleeing intolerable conditions, Paul jumped ship and made his way to Astoria to work in the salmon canneries. Wanting to increase his wealth above that of a low-paid cannery worker, he searched the Washington shoreline of the Columbia River for an ideal fish netting location and in 1915 he purchased land five miles downstream from Fort Vancouver.\u201d&nbsp;[Source: information sign located at Frenchman\u2019s Bar Park, visited 2006]<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" loading=\"lazy\" width=\"396\" height=\"607\" src=\"https:\/\/wpcdn.web.wsu.edu\/wp-extension\/uploads\/sites\/2079\/2019\/10\/HT1-Black-Walnut-2-396x607.jpg\" alt=\"Close view of a mature black walnut tree with multiple trunks and textured bark in a grassy park setting\" class=\"wp-image-16482\" srcset=\"https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2-396x607.jpg 396w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2-792x1214.jpg 792w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2-768x1178.jpg 768w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2-1002x1536.jpg 1002w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2-1336x2048.jpg 1336w, https:\/\/wpcdn.web.wsu.edu\/extension\/uploads\/sites\/83\/2019\/10\/HT1-Black-Walnut-2.jpg 1440w\" sizes=\"(max-width: 396px) 100vw, 396px\" \/><figcaption class=\"wp-element-caption\">Black walnut tree at Frenchman\u2019s Bar Regional Park<\/figcaption><\/figure>\n\n\n\n<p><em>Our pages provide links to external sites for the convenience of users.
