Senate Budget Bill Proposes Massive Sale of National Public Lands | Grand Canyon Trust

Up to 120 million acres of our public lands could be available for sale. If that happens, hunting, camping, birdwatching, and hiking opportunities would be lost forever.

Western voters overwhelmingly support keeping national monument protections in place, and ensuring Tribal Nations help lead the care of their sacred places.
→ 88% support monument protections

A helicopter for sure, and specifically a three-blade helicopter! The infrasound frequency is simply the number of blades times the revolution rate of the main rotor, and is typically around 20 Hz for three blade helicopters. Doppler shifted thereafter
