(BIVN) – A new video by Hawaiʻi Volcanoes National Park, coinciding with Black History Month, shows the story of the Buffalo Soldiers and the building of the Mauna Loa Trail.

From the National Park Service:

Most visitors to Hawaiʻi Volcanoes National Park never set foot on Mauna Loa Trail. Even fewer people know the remarkable story of the Black soldiers who in 1915 built a trail between the summit of Kīlauea and the nearly 14,000-foot summit of Mauna Loa volcano.

A new video from Hawaiʻi Volcanoes National Park, “Forging a Path with a 12-Pound Hammer,” celebrates Black History Month and the story of the African-American soldiers who built the remote 30-mile trail. The 10-minute film is available free to everyone on the park website.

Why would these enlisted men, who faced segregation even in racially diverse Hawaiʻi, undergo such a grueling task? Dr. Thomas A. Jaggar, founder of the Hawaiian Volcano Observatory, needed a route so geologists could reach and study the distant summit of Mauna Loa. At Jaggar’s request, soldiers from Company E of the 25th Infantry Regiment stationed at Schofield Barracks on Oʻahu, were assigned to construct Mauna Loa Trail.

Using only a 12-pound hammer and gunny sacks to move rock, these tough men toiled on the harsh, rain-soaked slopes of Mauna Loa. Thirty-nine days later, the Buffalo Soldiers finished the job.

Between 1915 and 1917, six companies of the 25th Infantry came to what is now Hawaiʻi Volcanoes National Park. In addition to building Mauna Loa Trail, the Buffalo Soldiers helped measure lava within Halemaʻumaʻu crater and were among the first to recreate at the newly established Kilauea Military Camp.

Black history is American history. During February, and throughout the year, National Park Service sites, programs, and digital platforms provide resources to connect with, and reflect on, African American history and heritage.
