  1. Evidence stance: supports · Evidence details

    The official Forest Service Convict Lake hiking map depicts a continuous dotted hiking route around the lake. The retained south-shore trail reaches the road and cul-de-sac on the lake's east side; the mapped loop follows a road connection, returns to an east-side lakeshore trail, and then uses another road connection through the boat-ramp and trailhead-parking area to rejoin the retained north-shore trail. The map does not publish individual leg mileages or reusable line geometry for these three mixed-surface connections.

    Retrieval time does not establish when an event occurred.

  2. Evidence stance: supports · Evidence details

    The July 2026 USGS Transportation service returns the Convict Lake Road and Boat Launch road features plus a paved 0.34564349-mile CONVICT LAKE VIS trail. Their geometry matches the road-trail-road loop closure depicted by the official Forest Service hiking map. The south road feature intersects the paved trail endpoint within 0.4 meter; the north road and retained trail endpoints match within approximately 1.4 meters.

    Retrieval time does not establish when an event occurred.
