The archived outline of the Red Bank Fire spans about 8.1 km from west to east and 9.9 km from south to north. CAL FIRE places the incident at Off Hammer Loop Road and Petty John Road, West of Red Bluff. The mapped boundary provides a second way to locate the event: it shows the extent around that reference location.

What the perimeter shows
The two spans differ by only 1.8 km. That does not make this a circular burn: the dimensions measure the outermost coordinates, leaving indentations and gaps invisible. Use the polygon itself, rather than its enclosing rectangle, to check whether a location intersects the footprint.
Two estimates of area
The incident report gives 8,836 acres; the interagency feature stores 8,822.0 GIS acres. The mapped value is 14.0 acres below the reported value (0.16%). This compares two published measurements, not two observation times. The difference cannot be read as fire growth.
CAL FIRE also records structures destroyed: 2. Those counts come from the incident record. A building inside the perimeter cannot be assigned a damage category from this map alone.
A similar-sized fire for comparison
The Saddle Ridge Fire of 2019 is the closest match by reported acreage in this 100-case collection (8,799 acres). Its mapped spans are 11.4 by 9.4 km, west–east then south–north, versus 8.1 by 9.9 km here. The longer axes run in different directions. Matching on acreage would miss that contrast.

Spans use the geographic extremes of a generalized boundary, converted to kilometres at its middle latitude. They are approximate map dimensions, not distances travelled by flames. The GIS acreage is the source attribute, not an area recalculated from the simplified outline.
