I enjoyed a nice quiet morning hike on this Father's day and first day of summer. Unusual sightings included a turkey asleep up in a tree, and a new lifer: the Northern Pygmy-Owl. I spotted a quite small bird landing on a high tree branch, out in the sunlight. I couldn't see what it was in the camera viewfinder, but I didn't expect it to be an owl!

The above hashes-<date>.txt file contains SHA-256 hashes of all the photos
from this shoot. The hashes-<date>.txt.sig is a signature of that hashes
file, created with my PGP key. The signature file
itself was written to both the Bitcoin Cash and Algorand blockchains, in the
OP RETURN and Note fields respectively, using the transactions below.
In short, this proves that these photos and the signature both existed at the time the
transactions were written to the Bitcoin Cash and Algorand blockchains.
