A.H. Marshall was the first person to successfully climb each U.S. state highpoint. He completed the task in 1936 after standing atop Hoosier Hill.- Solomon Sea Plate (Wikipedia)
The Solomon Sea Plate (also known as the Solomon Plate) is a minor tectonic plate to the northwest of the Solomon Islands archipelago in the south Pacific Ocean. It roughly corresponds with the Solomon Sea east of Papua New Guinea. The plate boundaries are associated with high earthquake activity as part of the New Britain subduction zone.
- Hoosier Hill (Wikipedia)
Hoosier Hill is the highest natural point in the U.S. state of Indiana with a claimed elevation of 1,257 feet (383 meters) above sea level. Hoosier Hill’s claimed elevation is based on SRTM digital elevation data which is now considered to be outdated. Using newer elevation tools such as USGS’s 3DEP, the top of Hoosier Hill is closer to 1,255.48 feet (382.67 meters) above sea level. Hoosier Hill is in the rural area of Franklin Township, Wayne County to the northwest of Bethel. The nearest intersection to the high point is Elliot Road and County Line Road. The nearest major landmark is Interstate 70 and Richmond 11 miles (18 km) to the south.
