Claim: Flourmill Volcanoes,  a small volcano range near the northern boundary of Wells Gray Provincial Park in Canada, obtained its parasitic cone, with a breach on the northern side to permit  drainage of a lava lake in the crater, due to renewed volcanism
Evidence: The Flourmill Volcanoes, also known as The Flourmills, are a small volcano range near the west boundary of Wells Gray Provincial Park in east-central British Columbia, Canada. A breach on the south side of the cone permitted drainage of a lava lake in the crater.
