The Arizona Geological Survey is experimenting with new ways of communicating geology
and geologic stories to Arizonans and K-12 educators.

AZGS has produced its first-ever map story which follows geologist Steve Rauzi and a team of
geoscientists as they raft through Grand Canyon.

“In a sequence of 29 captioned images, you’ll see Grand Canyon and some of its tributary
canyons as a geologist sees them. Rauzi fingers individual rock units and puts a face – of sorts –
to the names of famous rock formations: Devil’s Ramp and Vulcan’s Forge – products of the
Pleistocene Uinkaret volcanic field, Kiabab Limestone, Coconino, Tapeats and Muav Sandstone,
Bright Angel and Hermit Shale, the Redwall, Temple Butte, and Bass Limestone, and the Vishnu Schist.

Steve and his companions ramble across ancient stromatolite beds – some of Earth’s earliest life forms,
bushwhack across faults and massive rockfall deposits, and close in on the Vishnu Schist (river-mile 78),
Arizona’s oldest rock formation, at the bottom of Grand Canyon’s inner gorge. At river mile 98,
you’ll see a dory run Crystal Rapid, and at river mile 179 scout Lava Falls Rapids from a beach safely upstream.”

You can begin the journey here: A Geologist in Grand Canyon – Map Story. The graphic below shows the
main page and the third image. Mousing over the inset on the right allows you to expand the image.
Clicking the “x” on the bottom right of the expanded image returns you to the main page.

1. Great idea - but I wish the captions were readable while the image is expanded!

And you could go from one expanded image to another rather than closing the expanded image, going to the next, expanding the image, trying to read the caption and applying it to the expanded image overlying it...

Thanks for the link - I'll back to it another day.

2. Probably the closest I will ever get to rafting through the Grand Canyon

Thank you, it is awesome.
