Beyond the NW tip of Lake Baikal is the Tunkin (or Tunka) Depression volcanic field, shown in this September 2019 Planet Labs satellite image monthly mosaic (N is at the top; this image is approximately 170 km across). The field is the surface manifestation of a rift zone and contains five main groups of scoria cones and lava flows that were produced during the late-Pleistocene to Holocene.
