ForeFlight’s High Resolution Basemap displays more mountain peak markers near terminal areas and elsewhere for enhanced hazard awareness. Zooming the map into any terminal area will reveal all peaks and associated altitudes within 15nm of the airport, and zooming into any mountainous region will display a greater number of peaks as well.
