5. What is indicated by the two light gray shaded areas that cross the river above False River Lt. (mile 251.0 AHP)?

The light gray shaded areas indicate utility crossings, which are charted areas spanning the river and representing pipelines, cables, or combined utility corridors. These shaded bands alert mariners to areas requiring caution for anchoring, dredging, or grounding, and are distinguished from symbols representing aerial cable crossings, bridge construction, or ferry routes.
