Mauna Kea, the tallest mountain in the world from base to peak
Mauna Kea

Rising majestically from the heart of Hawaii’s Big Island, Mauna Kea is not just a dormant volcano; it’s a sacred and revered place in Hawaiian culture. This stunning volcanic peak reaches an elevation of 13,796 feet (4,205 meters) above sea level, making it the highest point in the entire state of Hawaii. Mauna Kea is not only a geological wonder but also a place of deep spiritual significance and an internationally renowned center for astronomy and stargazing.

Hawaiian meaning “Mauna a Wākea,” Mauna Kea is the name of a dormant volcano on the Hawaiian island. At 4,207.3 m (13,803 ft) above sea level, its top is the second-highest mountain of an island on Earth and the highest point in the state of Hawaii. The summit is around 38 meters (125 feet) higher than its larger neighbor, Mauna Loa. With a wet prominence of 4,205 m (13,796 ft), ranking fifteenth in the world among mountains, and a dry prominence of 9,330 m (30,610 ft), Mauna Kea is very conspicuous topographically for its height.

Because of its dry prominence, which is higher than Mount Everest’s elevation above sea level of 8,848.86 m (29,032 ft), some authorities have declared Mauna Kea, with its submarine base, to be the world’s highest mountain. Based on topographic isolation, Mauna Kea is rated eighth.

It passed the most active shield stage of life hundreds of thousands of years ago since it is around one million years old. Its lava is more viscous in its present post-shield form, giving it a steeper profile. Its adjacent volcanoes don’t have the same harsh aspect as this one because of late volcanism, which also caused cinder cones to form, rift zones to become dispersed, glaciers to accumulate on the top, and weathering caused by the dominant trade winds.

Since its last eruption between 6,000 and 4,000 years ago, Mauna Kea is believed to be dormant.

Tallest Mountain in the World

The north face of Hawaii’s Big Island is home to the 13,796-foot (4205-meter) Mauna Kea Volcano, which towers over the beaches of Kohala. enormous Standing 33,476 feet (10,204 meters) above its base on the Pacific Ocean bottom, Mauna Kea is the world’s highest mountain. In contrast, Mount Everest is the tallest mountain on Earth, rising 29,029 feet (8,848 meters) above sea level.
The age of Mauna Kea exceeds one million years. It is not regarded as extinct, even though the last eruption is thought to have happened about 4500 years ago. Since it is a dormant volcano, there is still a chance that it will erupt once again in the future.

Recent seismic activity beneath Mauna Kea Volcano has raised concerns about a possible eruption, though it’s important to note that earthquakes aren’t always direct indicators of imminent volcanic activity. Nevertheless, scientists anticipate that Mauna Kea will experience another eruption in the future.

To closely monitor subsurface movements, seismometers and a single GPS receiver (operated by NASA’s Jet Propulsion Laboratory) are strategically positioned on Mauna Kea itself. Additional monitoring instruments are placed on Mauna Loa to the south and Kohala to the north, providing scientists with critical data.

Shield Volcanoes

As with all volcanoes on Hawaii Island, Mauna Kea is a shield volcano. These types of volcanoes are characterized by their large, wide, and gently sloping sides. The summit of Mauna Kea, shown in the image below, is a classic example of a shield volcano.

This shape is a result of the fluid lava that flows gently across vast distances during eruptions, forming broad sheets and layers as it cools. This type of eruption is commonly referred to as a “Hawaiian eruption” due to its prominence in the Hawaiian chain.

The Cultural Significance of Mauna Kea

In the Hawaiian language, “Mauna Kea” is a shortened version of “Mauna a Wakea.” Wakea represents the sky father, making Mauna a Wakea the mountain that belongs to the sky. The name is often interpreted as “White Mountain” due to the frequent presence of snow at its summit. Mauna Kea holds immense sacred value in Hawaiian culture.

If you plan to visit the summit, prepare for cold weather. Even when there’s no snow, temperatures can be 40 degrees or more cooler than at the beach. Keep in mind that the road to the top is often closed due to snow and high winds, so it’s essential to check the current conditions at the Mauna Kea Weather Center before your journey.

Hiking on Mauna Kea

A short trail of approximately 0.3 miles (0.5 km) leads from the top of the summit road to the actual summit of Mauna Kea Volcano. The views from this vantage point are truly spectacular, but be prepared for high winds and cold temperatures.

For those seeking a more challenging adventure, consider a hike to Lake Waiau, located at an elevation of 13,025 feet (3,970 meters). The easiest starting point for this hike is approximately 2 miles below the Mauna Kea summit. Hikers should be in good physical condition, wear appropriate hiking shoes (no sandals), and dress warmly.

From the ridge above the lake, you can catch a glimpse of some of the telescopes at the Mauna Kea Observatory.

The Mauna Kea Observatory

The Mauna Kea Observatory is a world-renowned astronomical research facility with more than a dozen giant telescopes aimed at exploring the depths of space. The observatory’s location offers clear and crisp high-altitude air, providing breathtaking views in all directions.

The image of the Mauna Kea Observatory below was captured from the slopes of Mauna Loa, approximately 20 miles to the south of the Mauna Kea summit.

Mauna Kea Summit Tour

A visit to the Mauna Kea Observatory is a must, and one of the best ways to experience it is through the Mauna Kea Summit Tour. You’ll travel in the comfort of a luxury SUV to the summit of Mauna Kea, where you can admire the impressive array of telescopes and enjoy views that seem out of this world, nearly three miles above the ocean.

During the journey to the summit, you’ll make a stop at the Onizuka Center for International Astronomy Visitor Information Station. This serves as an important acclimatization point to the high altitude. The visitor center offers a wealth of information, educational videos about the volcano and its telescopes, and a well-stocked gift shop. Light snacks and drinks are provided before continuing to the summit.

Driving to the Top of Mauna Kea

While it is possible to drive to the Mauna Kea summit and Observatory, the 7-mile road beyond the visitor center can be treacherous. It’s highly recommended to use a 4-wheel drive vehicle due to the rough, steep, and unpaved sections of the road. In fact, most rental car companies explicitly forbid their vehicles from being driven on the Mauna Kea summit road. Therefore, joining a Big Island volcano tour is often the safest and most enjoyable option.

Even if you’re driving your own car, it’s wise to spend some time at the Visitor Information Station to acclimatize to the high altitude. The air is significantly thinner at this elevation, so it’s essential to drink plenty of water and stay at the visitor center for at least 30 minutes before proceeding to the top.

At the summit, there’s a short yet steep path that leads beyond the parking area to the actual Mauna Kea summit. This walk offers breathtaking views. Alternatively, you can explore the impressive array of Mauna Kea telescopes and stay for a mesmerizing sunset. Sunsets at nearly three miles high are known for their dramatic beauty.

If you decide not to make the full ascent, the drive along Highway 200, crossing the Humu’ula Saddle (the Saddle Road), offers fabulous vistas of both Mauna Kea Volcano to the north and Mauna Loa Volcano to the south on clear days. This drive is a scenic delight that shouldn’t be missed.

In summary, Mauna Kea is a geological marvel and a site of cultural significance. Whether you’re interested in astronomy, hiking, or cultural exploration, a visit to Mauna Kea promises to be a memorable experience.
