during my time in alaska, i was in awe in many moments. but nothing felt as breathtaking — and unexpectedly alarming — as being in a sea of ice.

i always hear about the glaciers melting and that coastal areas will be underwater in a couple of decades. while that statement alone is terrifying, being in alaska raised some questions. what other visible changes can we see now due to climate change? how can we tell the story of climate change without words?

i learned more about the science and history of glaciers in alaska. for example, while they melt, they also tend to advance and retreat throughout the valley. so, when we went out into a fjord, i began connecting the dots — the glaciers leave imprints on the mountains, and that’s one of the ways scientists and environmental enthusiasts can study glaciers.

as i photographed ice and the mountains, i noticed some rusted terrain. these are called trimlines. as glaciers advance and retreat, they leave the rock bare, causing a line to form an iron-colored surface. what is alarming about this is how fast it’s occurring. tim martin, a lindblad expeditions naturalist aboard the national geographic sea lion, said some glaciers had advanced and retreated in the last five to 10 years.

before traveling to alaska, i would always note ongoing studies and research regarding climate change and the environment. yet, the clear visualization of trimlines brought me to realize that climate change doesn’t just exist in data but before our eyes.

we were three-quarters of a mile away and yet the glacier stood as a towering monument that was almost too large to comprehend. our boat’s collective silent awe broke when a sudden thunderous pounding traveled down the canyon like a booming heartbeat “ba-dum, ba-dum, ba-dum.” 

“did you all hear that?” naturalist tim martin asked excitedly. a large chunk of ice breaking off the face of a glacier caused the sound — in an event called a “calving.” in addition to being a naturalist for lindblad expeditions, martin teaches geology, astronomy, art, and earth science at elon university. he has 20 years of experience in his field and i was grateful he was our guide on the zodiac that afternoon in tracy arm. being with him in that hallowed place of geology was an inspiring experience. 

my time in alaska taught me that rocks are our eldest knowledge holders. understanding ice, glaciers, mountains, and rocks is like understanding the language of the earth. after this trip, i believe that when we understand and connect personally with the earth, we are more deeply inspired to protect it. 

building and destroying the southeast alaskan mountains

“geologically, southeast alaska is a confusing place,” martin said. “southeast alaska’s mountains are like a conveyor belt at the grocery store that doesn’t have a cashier or bagger. all the material moves and then piles up at the end, tumbling and rolling over each other.” the tectonic activity (the large plates of land and ocean that make up the earth’s surface) in southeast alaska is strange and unique. it has produced some of the most beautiful and complex landscapes in the united states. southeast alaska has all three standard types of rock, sometimes several occurring in the same rock face. however, alaska has an iconic fourth kind of rock.  

“you know,” martin said, as he threw his whole upper body over the bow of the zodiac. “ice is a rock too!” martin popped back into our zodiac holding a 30-pound chunk of crystal-clear ice that had been floating in the fjord. he passed the hefty ice cube to me, and as it melted on my lap i listened to him tell us about the power of ice.

if rock built alaska, ice carved it. more specifically, ice was the vessel through which rock carved rock. the last ice age, which was 115,000 years ago, brought massive deposits of snow, creating vast snowfields across alaska with ice a mile thick. as these massive glaciers advanced and receded in cycles, they scraped huge amounts of fine rock material –– like the world’s heaviest piece of sandpaper –– across the great mountains of southeast alaska over and over and over. 

because of the glacier’s erosive power, the fjords and bays of alaska have a distinctive u-shape. in contrast, rivers carve canyons in sharper v-shapes like the grand canyon in my home state of arizona. the u-shaped chilkat valley can be seen clearly from about 3,000 feet on an airplane.

of ‘quartz’ rocks can speak!

martin and i first bonded over our shared love of rocks and outdoor rock climbing. i found kinship with the only other person on the expedition who would respond to the phrase, “it’s just a rock,” with a shocked and confused, “it’s just a rock?!” 

as i asked martin more questions about tracy arm’s unique geological features, i came to a profound and simple realization. once you understand the clues, places like tracy arm become storybooks. you can read a 100-million-year-old story written by earth herself. a rock’s type, age, magnetism, location, contents, shape, and composition are all bits of information one can use to determine the details of the place you are. 

i practiced this when i was walking with martin on the beaches of iyoukeen bay. he began to pick up the clues of his surroundings — the rocks began speaking to him. he noted the abundance of limestone and marble and the beach’s location in alaska and in relation to the pacific coast. he confidently said, “this was the bottom of the sea floor long ago.” i was amazed.

i wanted to get in on the conversation, so as any good budding geologist would, i had my eyes glued to the ground during our hike down the beach. i spotted a very peculiar and enchanting rock, and of course, i took it right over to martin for identification. “halley picked up fossilized coral,” he announced to the group. realizing i had picked up a piece of ancient history, i took my time admiring its smooth surface, its patterned grooves, and its dragon-like scales. the picture of the ancient sea bed was becoming clearer. 

martin then spotted more fossilized coral, and this time he was able to make an identification. he told me one of the fossils was that of a horn coral, an organism that existed only in the devonian period, making that fossil a minimum of 350 million years old. 

martin’s knowledge and my curiosity were the keys that unlocked a deep well of ancient knowledge. by reading the clues that earth left us on that beach, we were able to transport ourselves to a land before our time. it was a humbling experience to put myself and my life on the geological time scale of earth. it made me think about the blip that is all of human life compared to the forever of earth. the earth has always and will continue to leave clues for us to understand her. the earth speaks. rocks speak. we just have to know how to hear them. if humans spend less time talking and more time listening, we might just be able to make our profound effect on the earth a positive one. 

it is a magical experience to be able to read the earth in her native language in alaska –– it is a way to connect and engage with the natural world. that connection to the natural world is critical right now because it is what inspires us to fight for the health and safety of earth’s wildest places. martin said the reason he loves exploring alaska is that “…coming to wild and unaltered places is the way we can read the story of life on this planet.” i couldn’t agree more.

i was grateful to feel that on the boat as well. everyone on board had gratitude for the spaces we were able to explore and learn from. alaska has a long history of extraction where people have come to take advantage of the resources, animals, and people there, and before my trip, i was nervous about contributing to that. but now after talking to the naturalists and other guests, i’ve come to accept that humans, just like other animals do need and use parts of the environment. our responsibility is to not cause damage and be as subsistent as we can. along with the attention to not take away too much, i also realized i need to give back to spaces i’m in. i took away food, water, memories, and knowledge from alaska, and in return i made sure to pick up trash, spread seeds, and not bother animals when i could. going back to dc, i’m eager to grow the connections i have to the natural elements of my urban space so that eventually with volunteering i help can grow forests where we once had a yard; a river where we once had a stream; a family where we once had a group of strangers. i’m so grateful for this experience and am eager provide you with alaska’s story around lipids, from candlefish to whales to oil reserves.

my intellectual curiosities were stoked by the seemingly endless knowledge of the many naturalists on board. the naturalists had incredible presentations about geology, glaciology, marine ecology, and even squid physiology (complete with a on-deck dissection of a squid we found on a beach)! i found myself falling deeper in love with the natural world and finding new exciting disciplines — like geology. i’ll be writing my story about the language of rocks — so stay tuned!
