They are sleeping in vehicles or on cots under a tent and braving weather that's chilly for Hawaii standards at Mauna Kea's 9,200-foot elevation.
They are also making sure they have bail money ready. Some say they're bracing to be arrested when the nonprofit company building the Thirty Meter Telescope intends to resume construction tomorrow.
Work was put on hold for two months after the arrests of 31 people blocking access to the site. On Saturday, telescope officials announced construction would start again. Those against the project say the USD 1.4 billion telescope will desecrate land held sacred by Native Hawaiians. Some say it's time to curb development on the mountain, where 13 other telescopes sit.
Astronomers revere the site because its summit at 13,796 feet is well above the clouds, and it provides a clear view of the sky for 300 days a year. There's also very little air and light pollution.
Kahookahi Kanuha is one of the people camped out near the Mauna Kea visitor center, from which he said it takes about 30 minutes to walk to the construction site six miles away. He was one of the people arrested in April.
