After the winter, Kendrick sent "Washington" under Gray out on a short trading voyage to the south. Departing on March 16, 1789, Gray visited Wickaninnish in Clayoquot Sound and cruised south looking for the Strait of Juan de Fuca. He collected many sea otter pelts in Clayoquot Sound and found the entrance of the Strait of Juan de Fuca before returning to Nootka Sound on April 22. Gray found the "Iphigenia" under William Douglas anchored at Friendly Cove, having arrived on April 19 after wintering in Hawaii. A few days later Funter's "North West America" arrived, also from Hawaii. Kendrick had moved "Columbia" to a cove known as Mawina or Mowina, today called Marvinas Bay, about deeper into Nootka Sound. He had fortified a small island and built an outpost on it, with a house, gun battery, blacksmith forge, and outbuildings. Kendrick called it Fort Washington. It was the first US outpost on the Pacific coast. Kendrick intended it to be the foundation of an American presence on the Pacific Northwest coast, and as a headquarters for controlling the fur trade. Over the summer Kendrick used the outpost and his friendship with the Nuu-chah-nulth to collect hundreds of furs from the region.
