Further eruptions occurred 90 ± 100, 800 ± 500, 3,740 ± 10, 7,390 ± 200 BCE, and 1,529 ± 28, 1,944 ± 29, 10,015 and 1,735 years before present. The last two were small eruptions. Tephra from an eruption that occurred about 2,000 years before present reached a thickness of in a peat bog away from Monte Burney. One tephra around 1805 BCE found at the Siple Dome in Antarctica may be linked to Monte Burney but the timing of the tephra is problematic. Two tephras at Fiordo Vogel and Seno Skyring have been linked to Monte Burney; they are dated 4,254 ± 120 and 9,009 ± 17 - 9,175 ± 111 years before present. The younger of these two eruptions influenced sedimentation in these water bodies and the adjacent vegetation. Reports from natives, mentioned in 1847, of a volcano at the end of a bay that makes the ground tremble probably refer to Monte Burney, which is visible on clear days from Almirante Montt Gulf. In 1910 a researcher concluded that the volcano had been active in postglacial time, given that pumice formations found around the volcano would not have survived glaciation.
