Fireworks echo through cellulose and chitin

I recorded the Sewanee annual firework display at a lookout spot across a mountain cove from the detonations. Before the pyrotechnics, the katydids made my ears ring, but the explosions out-shouted even the combined acoustic power of tens of thousands of singing insects.

Here is the finale of the show:

If you listen with earphones, you’ll hear the low-frequency roar of the fireworks rushing down through the mountain cove for five long seconds after the blast. From where I sat at the Proctor’s Hall rock, the echo ran from right to left, flowing down, like a dark bird launching from the cliffs to the fields below the cove.

Thank you to the Sewanee Volunteer Fire Department for their annual extravaganza of sound and light.
