Which location corresponds to the label Tower 438?

• A. The HWY 191 bridge over Pond Creek
• B. Pond SW of 1st bend in 89
• C. 438' Tower NW of prison
• D. Power line abeam large estate north of OLF Spencer

Answer: (C)

Labels for towers on aeronautical charts identify a specific obstruction by its height and location. The number after the word Tower is the height of that obstruction in feet. So a label like Tower 438 points to the 438-foot tower, and you then look for its described position on the chart. The only option that matches a 438-foot tower is the one describing a 438' tower located northwest of the prison. The other options describe different features (a bridge, a pond area, a power line) that don’t match the tower’s height, so they don’t correspond to the label.
