BUILT. DROPPED.
BUILT AGAIN.
A whole new rack. Every single year.

SPRING
DROP THE CROWN.
Many bulls cast their antlers in March or April. The permanent bony bases, called pedicles, stay on the skull.
Look above the ears: the rack is gone, but its foundations remain.
AI-assisted educational illustrations. Monthly snapshots show a representative Yellowstone sequence, not measured sizes. Growth continues between spring and summer snapshots; the hard rack then stays roughly the same size until casting. Timing, size, and form vary between bulls.
THE BIOLOGY / NPSThey don’t keep adding to the same crown.
