In October, Broughton was ordered to explore the lower stretches of the Columbia River, between present-day Oregon and Washington. With several boats from his ship, Broughton and his party navigated upstream as far as the Columbia River Gorge and on 30 October, he reached his farthest point, landing in eastern Multnomah County east of Portland and northwest of Mount Hood, which he named for Viscount Samuel Hood, Admiral of the British Fleet. Late in 1792, Vancouver, stymied by conflicting instructions over Nootka Sound, sent Broughton back to England via Mexico and the Atlantic, bearing dispatches and requesting instructions.
