Sequoian

the Pendraneth sink is a vast crater/impact site, long since consumed by the vastnesses of the endless high forest of sequoia. Roughly consistent canopy in spite of the Pendraneth sink.
Sequoian: a bowl within a bowl within a bowl as if sprouting from the remnants of the millennial impacts of some great celestial hammer. The ripples of impact radiating into and trough the mountains and across this broad continent. Tree instruments and monumental structures. Sculpted in growth. Humagogue populations about 40 a one, stayers much greater.
