since mount wilson in located in the san gabriels, would it be appropriate to call it a san gabriel valley icon

Mount Wilson is located in the San Gabriel Mountains, which are adjacent to the San Gabriel Valley. While it is certainly a prominent landmark and has significant historical and cultural importance, it is more accurate to refer to it as an icon of the San Gabriel Mountains rather than the San Gabriel Valley itself. The valley is primarily the lowland area, while Mount Wilson stands prominently in the mountain range above it. However, people in the valley and surrounding areas may colloquially refer to it as a local icon due to its visibility and significance to the region as a whole.
