After a week in the mountains, Herb realizes his Ridgeway is 4 minutes too slow.
Back at sea level in Alameda, his pendulum clock kept perfect time.
Elevating his clock from sea level to his mountaintop citadel resulted in it slowing.
Measured at sea level, the radius of the earth in Alameda is 6563 kilometers.
How many meters above sea level is Herb’s armor-clad citadel?
