| 16 Dec 1977 | Lawson Fire | Lawson, NSW | 150.43 | -33.71 | 720 | 771216A |
|
This fire started north of the Great Western Highway and west of the town of Lawson in the Blue Mountains. With a wind direction of 255° grid the fire started travelling to the east. However, the mapping shows clearly that the fire also moved to the north along a gully line. Note that there was a second fire coming off the Kings Tableland, south of the highway. The main feature to note is the marked right-angle bend in the rear of the left flank of the fire, in the gully. This is a diagnostic feature of VLS. Note also that there was intense spotting downwind of this. |

| In this digitised rendering, the beige colour on the digital terrain model is output from a model of sites prone to VLS under the prevailling winds. It is seen that, allowing from issues with hand-drawn fire maps from the 70s, the lateral spread on the left flank coincides with a deep valley. |
