- Tyndall’s mapped area jumps from zero on Sep 12 to 1.8 hectares on Sep 22; the page labels the reading flickering and suggests possible explanations.
Field notes
Records pair dated satellite readings with location, elevation, aspect, slope, and one-way approach details from trailheads such as Bear Lake and Mitchell Lake. A ground report can complicate the satellite picture: Mt Audubon is marked skiable despite a zero-pixel satellite reading, which the page says may miss a strip narrower than about 40 metres. The page cautions that cloud and shadow can affect readings, and that snow presence is not a safety assessment.
