Final answer:
Maunakea is the mountain associated with Wakea, the cosmic sky father, and is also a sacred site and home to a major observatory complex, which has been a point of cultural contention.
Step-by-step explanation:
The mountain associated with Wakea, the cosmic sky father, in Hawaiian cosmology is Maunakea. Maunakea is not only Hawaii's tallest mountain, but also holds significant cultural and spiritual importance for the native Hawaiian people.
Due to its elevation and clear skies, Maunakea is a prime location for astronomical observations, and it is home to the world's largest observatory complex. However, the construction of telescopes on this sacred mountain has led to controversy and opposition from native Hawaiians who wish to protect the sanctity of the site.
