I remember it when the costal radar installation still had a dome.
The wild growth has had its benign low level fire cycle interrupted. It used to be a low grade fire would mosey through every few years.
Then the stewards decided that every fire, no matter how small had to be promptly extinguished.
Rather than never having more than a few year’s worth of dead brush, it was allowed to accumulate for decades.
They opened Mt. Umunhum as a new park in Sept 2017. The roads, facilities, picnic huts, trails, parking areas, and visitor station at the top are amazing. The rotating radar antenna on top of the concrete foundation building ended service in 1980.
