Reader Kurt Helf sent a photo and a bit of information (indented).
Here is an image of me kayaking in Echo River, an underground river in Mammoth Cave National Park, as part of my duties as an employee of the Cumberland Piedmont Network. My colleagues and I were moving inflatable kayaks from one site to another, a process which was facilitated due to low water, the removal of a decommissioned dam on the Green River, and the removal of gravel from the river’s spring head. We were working on installing transects and stilling wells in two cave rivers as part of my Network’s long-term efforts to monitor cave aquatic biota at Mammoth Cave National Park. The image quality isn’t the best, but I was doing most of the photography so it’s the only image of me in the kayak.

What an interesting job!
Maybe he can send in some cool photos of the blind (eye-less) fish and some of the other fascinating critters that live in those waters.
Very interesting work.
Huh?
Oh, that’s what you mean. Oh, the number of times I’ve asked for permission to install something like that in our level-measurement systems, to be told “you’re not welding nowt in my mud pits!”
A really fascinating job.
Looks like you’re doing some great work down in them caves. Thanks for the link…fascinating Network.
Lookin’ like “Charon,” the oarsman who ferried souls of the newly deceased to the Underworld across the river Styx, Kurt.
Mammoth Caves is a strange and wonderful place. Beats goin’ to the office every day, I’ll bet.
Thanks for sharing your work with us!
Nice photo, a little reminiscent of a suited-up crash test dummy, but I’m sure you are no dummy!
Looks like a very interest job and a lot of fun as well. Enough to make a long retired person go back to work.
You can always volunteer. Contact your local wildlife refuge or similar facility and ask about volunteering. I do so regularly and enjoy it thoroughly. Also, see if your region has a Master Naturalist Program where you can learn a lot about your area’s natural systems and find lots of like minded people.
