Onondaga Cave (2)

Onondaga Cave is a wet cave. That means many of the formations are still active and the air in the cave is very moist. There is an airlock where the tour begins and ends. There are salamanders in the cave, but their numbers have declined with the bats (White Nose Syndrome); the salamanders eat the bat droppings and there are not enough to sustain as many salamanders and before. We didn’t manage to see any.

There is a river that runs through the cave. At one point you can hear the water moving but when you look at it from above it seems very still! They know where the water goes but not where it comes from!

On the way home we stopped at Bennett Spring State Park near Lebanon MO. It was raining so the only picture I took was of a painted glass window! We drove down to where the spring emerges and then back to I-44 along a road through the forest….lots of dogwoods in bloom in the understory. It was a grand finale to the day trip even with the rain!

Gleanings of the Week Ending April 19, 2025

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Survey: US Public Spaces Not Meeting Community Needs – Funding for maintenance and basic improvements seems to be the key issue.

I tested some of the most popular ways of meeting new people. Here's what I found – The author engaged in 4 ‘hobbies’ and assessed their effectiveness in fostering social connection: team sports, bouldering, creative writing sessions, and a life drawing course. Evidently, they all worked for her! For me – my volunteer activities (with Missouri Master Naturalist and my county’s Friends of the Library) are the way I meet new people; I tend to like the triadic interactions (attention both to each other, and to an object or activity of mutual interest) that volunteering provides.

These Unassuming Artifacts from King Tut’s Tomb Could Tell a Remarkable Story – Originally the 4 small unbaked earthen dishes were thought to be stands for the nearly four-foot high gilded wooden staffs…but a new study proposes that the clay troughs would have held libations, most likely of water, aimed at the purification and rejuvenation of Tutankhamun in the afterlife, a rite known as the Awakening of Osiris.

Cuts to the National Weather Service May Have Serious Impacts on National Parks – And for everywhere else too. Weather impacts everybody.

New research boosts future whooping cough vaccines – My father – now in his 90s – almost died from whooping cough as a young child. Deaths have become less common since the vaccine although they are still in the double digits in the US. In 2024, several outbreaks left public health officials and hospitals scrambling to accommodate a sudden influx of patients, primarily infants, who are often too young to be vaccinated and suffer the most severe symptoms. I’m glad that a new vaccine may be more effective and longer lasting than the one we have now.

Study Reveals Mercury-Poisoned Industrial Age Child – A three- to four-year-old child died in France sometime in the 18th or 19th century. The youngster suffered from rickets and scurvy likely caused by poor living conditions during the Industrial Revolution. But there were also high levels of mercury in his bones and teeth. The study ruled out sources of mercury contamination and concluded that the child had been administered the toxic metal as a cure for his ailments, which ultimately killed him.

At 97, Endangered Tortoise Becomes Oldest First-Time Mom of Her Species with Four New Hatchlings – Four Galapagos tortoise hatchlings at the Philadelphia Zoo!

Celebrating Seeds – From The Prairie Ecologist. So many obstacles must be overcome for a seed to become a mature plant producing seeds….continuing the cycle of the species.

Antarctic Sea Ice Plunged in Summer 2025 - In 2025, summer sea ice in the Antarctic tied for the second-lowest minimum extent ever recorded in the 47-year satellite record. It’s not yet clear whether the Southern Hemisphere has entered a new norm with perennially low ice or if the Antarctic is in a passing phase that will revert to prior levels in the years to com

Global Economy More Vulnerable to Warming Than Previously Thought - By rattling supply chains, future storms and heat waves will also send ripples throughout the global economy, inflicting costs far higher than models currently show. No country is immune.

Science of Terra Nova British Antarctic Expedition

The Terra Nove expedition took place between 1910 and 1913. It was led by Captain Robert Falcon Scott who died after making a last entry in his diary on March 29, 1912; his death along with the men in his party, overshadowed the scientific contributions at first.

The 12 scientists who participated—the largest Antarctic scientific team of its time—made important discoveries in zoology, botany, geology, glaciology, and meteorology. Volumes 4-8 of the Natural History Reports from the expedition were published between 1917 and 1924; they are my free eBooks selections for this week…freely available on Internet Archive.

Geology Course Experiences – April 2025

Over the past month, the online geology course has moved along slowly with only another 2 chapters covering waste management/landfills and landslides. There was a week-long pause for Spring Break. I am glad I chose this version of the geology class (It’s titled ‘Earth: The Survival Guide’) since it provides a background for items in the news that have a geologic component. The syllabus for the next few weeks shows a significant uptick in topics with 4 chapters before the last exam on May 1. It seems like the course pacing is dramatically skewed toward the end.

I was disappointed that the scheduled field trip day was canceled because of weather (rain the previous days and the scheduled day, flash flooding and river flooding). Evidently there is not going to be another attempt. I’ll have to make do with my own observations as I travel around the state…and the geology field trip with Missouri Master Naturalists that is scheduled for early May; hopefully the weather will be better for that one.

The labs were also impacted by spring break. Topics were:

  • Groundwater contamination investigation that involved samples to be tested for nitrates, total dissolved solids, pH, and salinity…then pinpointing where contamination was coming from using a contour map of industries and where the samples were collected.

  • Streams and rivers using topographic maps to observe how river move along the surface and the observable structures from the interactions between water and the surface (things like natural levees and oxbow lakes).

  • Geologic maps – looking at the geographic distribution of rock units exposed at the Earth’s surface. Maps of Webster County MO, Bright Angel Quandrangle, AZ (part of the Grand Canyon), and the Williamsville Quadrangle, VA (part of the Appalachian Mountains).

The ‘streams and rivers’ lab was not on the original syllabus and there has not been an update showing which of the labs will be dropped. I hope the ones on Caves/Karst and Shorelines will still be part of the semester.

I am anticipating a flurry of activity between now and the end of the semester! There are a lot of textbook chapters in the syllabus that we haven’t done yet.

Gleanings of the Week Ending April 12, 2025

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Doctor shortages have hobbled health care for decades − and the trend could be worsening – It does seem like it is getting harder and harder to make an appointment with my doctor…and I have yet to see the same doctor twice for my annual checkup since we moved to Missouri. This article provides some background into why the US is increasingly short of doctors.

Your neighborhood might affect your risk of dementia - Most studies of risk factors for Alzheimer's disease focus on the individual level, not the community level. Of course, intervening at the community level is challenging, but prioritizing disadvantaged communities may be an effective way to mobilize resources for older adults and provide avenues for reducing the risk of dementia for the overall community.

Mangrove Pioneers - On the ground, a team surveying tidal marshes near the Florida–Georgia border in 2024 found red mangroves (Rhizophora mangle) and black mangroves (Avicennia germinans) growing 50 miles (80 kilometers) and 14 miles (23 kilometers) farther north, respectively, than their previously documented range. Landsat and other satellite imagery are valuable for monitoring marsh-to-mangrove transitions over larger areas and longer time frames. Conditions along the U.S. East Coast are conducive to mangrove territory expansion - less-frequent extreme cold events and rising winter temperatures in the region as contributing factors to the trees’ survival.

These Carnivorous Snails Slurp Earthworms Like Spaghetti – Snails in New Zealand….the short video is worth watching!

Why Norway is restoring its Cold War military bunkers - Norway is a land with many bunkers. At the peak of the Cold War, the sparsely populated, mountainous country had around 3,000 underground facilities where its armed forces and allies could hide and make life difficult for any invader. Norway is reactivating two of their most iconic underground structures of the Cold War. The role of the reactivated base which has had structural and equipment upgrades is to help the "resilience and survivability" of Norway's F-35s in the face of a Russian attack.

Are Hairstyles the Key to Unlocking Art History’s Most Famous Portraits? - Hairstyling has always been a way that women exacted agency over their self-presentation.  Paintings and sculptures can be rare visual records of these carefully chosen, and ephemeral, hairdos—which, unlike fashion garments, can’t survive and be passed down. (Although some historic wigs and clip-ins have stood the test of time and made it into museum collections.)

Making Sense of Butterfly Declines - Over the past two decades, the total number of butterflies across 554 species has plummeted by 22%. That means a loss of about one butterfly out of every five observed since 2000. This alarming trend underscores the severity of the decline, with many species experiencing drastic reductions in their populations. Three ways to help butterflies: plant native, plant native milkweed (i.e. native host plants), don’t spray.

2,000-Year-Old Wooden Houses Found in China - Houses in Shaoxing, Zhejiang, that date to the Warring States period (475–221 b.c.). The stilted and terraced wood-frame structures would have been covered with reeds and bamboo. The walls, made of interwoven wooden posts and thatch, retain numerous small holes, which archaeologists believe were left by grass ropes used to bind the structure together. Artifacts recovered from the site included primitive porcelain cups, red pottery tripods, ceramic urns, bronze drill bits, and plentiful remains of domestic animals as well as marine resources.

Retreating Arctic Glaciers Have Exposed 1,500 Miles of Coastline - Scientists tracked the movement of 1,500 coastal glaciers from 2000 to 2020, finding that retreating ice had unveiled hundreds of miles of coastline, largely in Greenland - revealing stores of precious metals…. but they warn that newly exposed coastline, which has not been cemented with ice, is vulnerable to erosion and landslides.

Life Magazine from 1937

Internet Archive has digitized versions of many Life Magazines. I have been browsing through them – slowly since there was an issue for each week. As I looked at the issues from 1937, I thought about my parents; they started school that year. They were probably still very focused on things going on within their family and small community rather than the broader world…but the world was heading into a time of turmoil. Looking at the way Life was covering those events seems relatively naïve now! The sample images (one from each weekly magazine) show a variety of topics the Life editors chose to cover over the course of the year. Most of the ‘color’ pages of the magazine were advertisements.

2 Months with my Nikon Coolpix P950

The most significant experience with my newish Nikon Coolpix P950 was our trip to Loess Bluff’s National Wildlife Refuge; there were three blog posts from that trip (one, two, three). My favorite image that the new camera captured was a video of trumpeter swans…trumpeting!

There were a few photos I took around my spring yard – crocus and a pinecone in the grass. I notice the slight increase in weight from my previous camera…not a positive for the new one.

The camera autofocus is not as good in lower light as my previous camera…or maybe it is the ‘through the window’ aspect of the photos I take while we are making Feeder Watch observations.

I am determined not to revert to my previous bridge camera (Canon Powershot SX70 HS) but I find myself using my small point and shot camera that I can slip in a pocket for times I don’t anticipate needing the additional zoom power of the heavier camera!
