I co-led an Osher Lifelong Learning Institute (University of Alabama in Huntsville) outing on August 2, 2024, to observe 200-400,000 gray bats emerge at Sauta Cave National Wildlife Refuge. We arrived at 7:00 PM anticipating the 7:45 PM sunset triggering the mass exodus. I first visited the cave in September of 2023, realizing that the bats had already migrated from their summer home. We were hoping for greater success on this excursion.

 

Arriving at the Refuge

 

We arrived an hour before sunset and entered the 264-acre refuge to explore with time to spare before posting at the cave for the grand sunset bat show.

 

 

 

 

I recorded this 59-second video as we entered the refuge.

 

The cave lies just several hundred feet beyond the parking area. We stopped by the viewing deck which is positioned to see the gated and secured cave, the sheltered forest within a natural amphitheatre backed by a cliff face framing the cave opening, and surrounded by a bowl of protective forest with open sky above.

 

The setting reminded me of an Appalachian Mountain cove, rich with deep limestone-derived soils, dark shade, abundant seeping moisture, and lush shrub and tree growth. Elderberry loaded with ripening fruit stood at the deck railng (left). Tall ironweed in full flower was nearby at right.

 

 

 

The cave literally emerges from the rock ledges. I wondered how many millennia have gray bats sought diurnal seasonal shelter at this location. US Route 72 is within earshot. That’s relatively recent in the tale of Sauta Cave. To what extent has it affected the bats? Lake Guntersville’s backwaters lap at the old road edging the Refuge. The lake stretches 75 miles and covers 69,100 acres of easy pickings for insect-foraging bats. Prior to the 1930s, the undammed Tennessee River extended those same 75 miles. Have the bats noticed the change since engineers completed the dam? When Native Americans first occupied the valley 13,000 years ago, did the bats notice…or care? The Refuge placed steel bars at the cave’s entrance. Prior to that, I suppose humans occasionally sought shelter. Did the bats mind?

 

Awaiting the Period of Emergence

 

With time to spare before sunset triggered bat emergence, we walked the old road that took us past the cave and its viewing deck, Lake Guntersville backwaters and marsh to our left and forested hillside to the right. A typical humid summer evening embraced us.

 

This 59-second video captures the group passing time returning to the cave as the sky darkened prematurely ahead of the sunset.

 

We crossed a power line, presenting a view of the wooded hills, wherein the cave resides, and the clouds building to our west.

 

We encountered bears foot in flower along the trail. I suppose its large leaf earns the moniker.

 

Brown eyed Susans also flourished at the road’s edge.

 

A hillside seepage crossed the old road and entered the Lake Guntersville mud flats.

 

 

Rain began in earnest as we returned to the viewing platform. I recorded this 57-second video as we hunkered against the passing shower.

 

One who is uncertain about being in the presence of so many airborne mammals might find the cave and its environs dark and foreboding. I viewed the rain-drearied entrance with anticipation and exhilaration. I awaited the first emergents nearly breathlessly. Raw Nature inspires me to the core.

 

The iron gate keeps humans out, but does not impede bat passage.

 

Alas, our friends did not disappoint us. Tons of insects were about to sate the massive appetite of hundreds of thousands of hungry bats. I wonder how much each bat consumed. What insect species and by what proportion? How far did the bats range? What other colonies intermixed over the Sauta foraging range? Nature’s mysteries never fail to encourage me to look more deeply. Albert Einstein shared my sentiments:

Look deep into nature, and then you will understand everything better. I have no special talents; I am only passionately curious.

 

Here is the 59-second video I recorded during peak flow:

 

Because bat movement is rapid, I tried this 35-second video that ends with a brief period recorded in slow motion:

 

Nature-Buoyed Aging and Healing Reflections

 

I’m drafting the narrative for this photo essay on September 6, 2024, 18 days since my total right knee replacement surgery. We visited Sauta Cave 18 days before the replacement, within the range of growing pre-operative anxiety. I knew what to expect from having my left knee surgery in January 2024, and that heightened my angst. Recovery physical therapy is demanding and painful. Serious swelling exacerbated my January/February rehabilitation. By August 2, 2024, my left knee performed better than it had in many years, and here I was about to muscle through another joint surgery and rigorous PT.

Good news! Just two-and-one-half-weeks since the right knee surgery, I am walking in the neighborhood with only a trekking pole, having graduated from a walker to a cane and now cane-free. I’ve averaged two hours of PT per day. Swelling has not been unusual. My recovery pace far exceeds what I experienced in January. I see ahead an enticing sequence of greenways, gentle woods trails, and eventually tough, hilly, and rocky forest ventures as we enter the joyous cool days of our dormant season.

Noone among us knows how many more hikes lie before us.

Thoughts and Reflections

 

I offer these observations:

• This grand show is eternal. It is always sunrise somewhere; the dew is never all dried at once; a shower is forever falling; vapor is ever rising. Eternal sunrise, eternal sunset, eternal dawn and gloaming, on sea and continents and islands, each in its turn, as the round earth rolls. (John Muir)
• Look deep into nature, and then you will understand everything better. I have no special talents; I am only passionately curious. (Albert Einstein)
• When we contemplate the whole globe as one great dewdrop, striped and dotted with continents and islands, flying through space with other stars all singing and shining together as one, the whole universe appears as an infinite storm of beauty. (John Muir)

Inhale and absorb Nature’s elixir. May Nature Inspire, Inform, and Reward you!

If only more of us viewed our precious environment through the filters I employ. If only my mission and vision could be multiplied by untold orders of magnitude:

Mission: Employ writing and speaking to educate, inspire, and enable readers and listeners to understand, appreciate, and enjoy Nature… and accept and practice Earth Stewardship.

Vision:

• People of all ages will pay greater attention to and engage more regularly with Nature… and will accept and practice informed and responsible Earth Stewardship.
• They will see their relationship to our natural world with new eyes… and understand their Earth home more clearly.

Steve’s Four Books

 

I wrote my books Nature Based Leadership (2016), Nature-Inspired Learning and Leading (2017), Weaned Seals and Snowy Summits: Stories of Passion for Place and Everyday Nature (2019; co-authored with Dr. Jennifer Wilhoit), and Dutton Land & Cattle: A Land Legacy Story (2023) to encourage all citizens to recognize and appreciate that every lesson for living, learning, serving, and leading is either written indelibly in or is powerfully inspired by Nature. All four of my books present compilations of personal experiences expressing my deep passion for Nature. All four books offer observations and reflections on my relationship with the natural world… and the broader implications for society. Order any from your local indie bookstore, or find them on IndieBound or other online sources such as Amazon and LifeRich.

I began writing books and Posts for several reasons:

• I love hiking and exploring Nature
• I see images I want to (and do) capture with my trusty iPhone camera
• I enjoy explaining those images — an educator at heart
• I don’t play golf!
• I do love writing — it’s the hobby I never needed when my career consumed me
• Judy suggested my writing is in large measure my legacy to our two kids, our five grandkids, and all the unborn generations beyond
• And finally, perhaps my books and Blogs could reach beyond family and touch a few other lives… sow some seeds for the future
