The archived outline of the Rough Fire spans about 46.5 km from west to east and 26.7 km from south to north. CAL FIRE places the incident at 5 miles North of Hume Lake and 2.5 miles to the southwest of Spanish Mountain 5. The mapped boundary provides a second way to locate the event: it shows the extent around that reference location.

What the perimeter shows
The longer dimension runs east–west and is about 1.7 times the shorter one. A circular buffer drawn around the incident point would hide that difference. A road or settlement at the same distance from the point could fall inside or outside the mapped footprint depending on its direction.
Two estimates of area
The incident report gives 151,623 acres; the interagency feature stores 151,546.8 GIS acres. The mapped value is 76.2 acres below the reported value (0.05%). This compares two published measurements, not two observation times. The difference cannot be read as fire growth.
A similar-sized fire for comparison
The King Fire of 2014 is the closest match by reported acreage in this 100-case collection (97,717 acres). Its mapped spans are 28.1 by 41.9 km, west–east then south–north, versus 46.5 by 26.7 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.
