Answered for Cicero, Hamilton County.
Common on stressed honey locust and on trees with mower or string-trimmer damage at the base — which is a genuinely avoidable cause. In Cicero, cicero has no public street-tree inventory, so species composition is not documented town-wide — but the age structure is: Morse Reservoir's roughly 35 miles of shoreline was about 95% built out with waterfront homes by 2020, and those lakefront lots hold the oldest, largest canopy in town, growing since the 1956 impoundment. Post-2015 subdivisions read very differently, with uniformly young front-yard stock, and ash is gone countywide after emerald ash borer reached all 92 Indiana counties by 2017. A canker that has girdled more than about half the trunk circumference is structural, not cosmetic.

Sunken dead patches on bark, sometimes oozing, often with cracked margins. Branches above the canker die back.
A canker that has girdled more than about half the trunk circumference is structural, not cosmetic. Small branch cankers can be pruned out; trunk cankers usually can't.
Prune out affected branches in dry weather, well below the canker.
