After gaining the Coast Miwok's trust, Drake journeyed to explore the inland area and visit their villages. Accompanied with crew members, Drake trekked on a Coast Miwok trail to traverse the Inverness Ridge and descend into what is now the Olema Valley. Fletcher described the village structures there as round subterranean buildings which came together at the top like spires on a steeple. Fletcher made further note of their culture by recording detailed characteristics of the Coast Miwok baskets stating they were water-tight, shaped like a deep bowl, and covered with a matted down of colored feathers. Such baskets were made only by the Coast Miwok, Pomo, Lake Miwok, Patwin, and Wappo peoples who were all concentrated near Drake's landing site. Additionally, Fletcher was the first person to make a written record of any of the 64 distinct language groups in prehistoric California, namely five specific Coast Miwok words: Hioh, Gnaah, Huchee kecharo, Nacharo mu, and Cheepe. These words noted by Fletcher are from a distinct language group, and Heizer wrote that they were unquestionably of Coast Miwok derivation, linguistic proof of Drake's contact with the Coast Miwok. Overall, the relations between the Coast Miwok and their visitors were peaceful and friendly, and the Miwok seemed to exhibit distress when Golden Hind sailed away.
