Trip Report: Group Leader: Mark Hougardy | Organization: Road Scholar | Date: August & September 2021 | Departures: 4 | Duration per Program: 6 days | Hiking Distance: 30 miles each departure | Participants: ~20 per departure | Type: Hiking | Note: The trip leader and participants were fully vaccinated against Covid-19 and Covid safety protocols were strictly observed. A big thank you to everyone for being considerate and recognizing the safety of your fellow travelers allowing all to better enjoy this program.
Sunny weather and pleasant temperatures greeted participants on 4 hiking programs exploring Oregon’s central coast. The focus of each program was learning about how the coast has changed especially over the last 100 years. Hikes included exploring the temperate rain forest, old-growth Sitka Spruce, the rugged Oregon coast, and the Oregon Dunes National Recreation Area which is one of the largest expanses of temperate coastal sand dunes in the world.
Our group was fortunate with sunny weather this week as our program was bookended by storms. Our local study leaders, who were well-versed in the area’s natural history, really brought the program to life – thank you for their expertise! This was a great trip to discover how the natural history of the central coast has changed, especially over the past 150 years. I’m happy to have helped with bringing my own experiences and knowledge to help such a wonderful program.

Crater Lake National Park never ceases to amaze the viewer, but this time the lake astounded me and my Road Scholar participants with some mysterious rings seen upon the lake’s surface.
These unusual rings were viewed near Wizard Island from Watchman Peak and were observed on August 29, 2019, between 9:20 am & 9:40 am (approximately).
That morning, my educational tour group had hiked to the summit of Watchmen Peak. We were treated to an expansive vista over an exceptionally peaceful Crater Lake. The gigantic body of water mirrored the sky as there was no wind, nor any waves caused by the island excursion boats. What we did see upon this flat liquid pallet were multiple “rings.” At first, the rings appeared to be raindrops to the west and southwest of Wizard Island (in the Skell Channel area), yet our perspective was 800 feet higher and three-quarters of a mile distant. These rings were sizable!
I had never observed such rings during multiple visits to the lake. Were these new? Had I not observed them before because of wind, light, or other surface conditions? -The mystery is afoot!
As my group arrived at the summit several of the participant’s phones reconnected with cell service. The group had been a couple of days without any service and a few people were eager to check email, news, etc. One person exclaimed that about an hour earlier (approx. 8 am Pacific) a 6.3 earthquake had struck off the Oregon coast. The question was raised, could a massive and distant energy release encountering a different density (energy waves traveling from rock then to liquid, especially upon a very still body of water) have allowed stored gases in a shallow area of the lake to escape, causing these rings?
It was intriguing, yet an earthquake some 200+ miles distant seemed remote. What there a more likely cause? The area in the Skell Channel area is relatively shallow (from 60 to 200 feet deep) compared to the rest of the lake, and has an abundance of underwater moss. The water at Crater Lake is known for its clarity and this massive biomass might have been bathing in a bounty of sunlight. The weather for several days prior had been mostly sunshine with only some rain that night…could these conditions have accelerated photosynthesis? What about springs in the area? Based on the ring images (especially the close-up image) this seems likely, but Crater Lake is essentially a closed system, its small watershed (the rim of the lake) means the lake receives all its incoming water from snow-melt and rain. There is supposedly some hydrothermal spring activity on the bottom of the lake, but this appears to be limited and at greater depths.
Was there a more likely explanation? I reached out to the Crater Lake Institute and the Oregon Master Naturalist program for help. I also included some photos of the curious phenomena, including one close-up, and several photos that were overlaid with Google Earth to help with identifying the location and determining the scale.
After a few emails were exchanged one cause of the rings’ formation was the most supported: “unusually strong photosynthetic activity by prominent beds of submerged plants, which occur in shallow waters around Wizard Island creating supersaturated oxygen levels, resulting in oxygen bubbles rising to the surface.” – Crater Lake Institute.
This sounds very plausible and I’m grateful for the feedback. I am curious if there is any research or photos showing this phenomenon in previous years. If anyone has any knowledge, please contact me. Seeing the rings was amazing and I hope to return on future clear summer days to gather some additional data.
Thank you to the Crater Lake Institute and the Oregon Master Naturalist program!
I enjoyed leading an 8-day outdoor spirited program in central Oregon for a group of 16. This was an inter-generational trip for grandparents and grandchildren. The tour was an exciting exploration of the natural and cultural history of the area. I’m so happy to have helped develop this interpretive program and I loved introducing others to this amazing landscape.

I’m happy to have been the leader on another great Road Scholar trip. This program introduced grandparents and grandkids to how fire helps forge every aspect of our life (homes/communities, food preparation, entertainment, arts, places we play, and our survival).
Leader: Mark Hougardy | Organization: Road Scholar | Date: June 2018 | Duration: 6 days | Participants: 28 | Type: Field Trips & Motorcoach
“Erupting volcanoes. Blacksmithing. Outdoor cooking. Glassblowing. A fire has countless uses, and incarnations, and has been paramount to our way of life since the beginning of our time. You and your grandchild will spark your desire to safely learn more about fire through interactive experiences with professional firefighters, survivalists, welders, and fire dancers. Discover how fire can create a delicate piece of artwork, as well as destroy entire forests and cities. Learn how to survive in the remote wilderness, and discover the inner workings of a city’s fire engine. Together with your grandchild, finally have the chance to play with fire as you discover why nothing can hold a candle to this learning adventure.”
Leader: Mark Hougardy | Company: Road Scholar | Dates: Three trips, July-August, 2017 | Participants: 15-25 per group | Type: 6-days of field outings and motorcoach travel in western Oregon
I enjoyed leading this Road Scholar trip for grandparents and grandchildren. It was a fun and educational opportunity for different generations to share time together exploring the world of animals. For my programs, I wanted to create a mentoring environment where, at the end of the program, everyone who is young at heart would think of themselves as beginning zoologists. A zoologist is a curious person (a scientist) who loves to learn about animals and everything they can teach us.
