فَعَلَوْتُ مُرْتَقَبًا عَلَى ذِي هَبْوَةٍ حَرْجٍ إِلَى أَعْلَامِهِنَّ قَتَامُهَا
Then I climbed to a lookout on a high, difficult, dust-raising rise, with dust extending up toward its landmarks.
Murtaqab is a lookout; dhī habwah describes a dusty rise, and aʿlām are prominent markers or heights. The image conveys a tactical vantage point rather than a general scenic mountain description.
