The contoured rings are stress fractures caused by contraction from grounding lines, and/or the weight of the ice as it lost its water support. The cracks then widened y sublimation, which made them apparent. Total length was about 2m. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/121bbeda-11ba-4745-9f4c-7db2a0ef8441/Detail+of+puddle+among+rocks+showing+stars.jpg Ice - Puddles Detail of a Puddle among Rocks and Showing Stars: A close look will find star formations and other spicules frozen into the sheet. The rings are stress fractures. The circles may be related to joints between fractures. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/38be6dc4-dd7e-418c-8b29-300749acb1c9/Detail+of+rectangular+puddle+showing+a+ring+of+holes.jpg Ice - Puddles Detail of a Rectangular Puddle Showing a Ring of Holes: This full puddle is shown elsewhere here. The holes were filled with clear ice which had air bubbles. Why they formed is unclear but are surely related to stress because they are concentric with the rings. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/1698245449901-GBQ1PMM96V8J5S4ZVXCS/Driveway%2BPuddle%2BB.jpg Ice - Puddles Driveway Puddle A: My driveway images show ice formed on a small shallow puddle on my old rough driveway. There are interesting dendritic formations, and curled fractures caused by stress around rough sections or small pebbles. These driveway images are of areas about 30 cm wide. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/1698245647824-2B4UENY5EN1VXYC5D7RT/Driveway%2BPuddle%2BA.jpg Ice - Puddles Driveway Puddle B: Sunlit Fractures Within Black Ice Upon Pebbles: The area was 7 cm wide in the horizontal direction. The fractures were caused by sagging when the water beneath detached from the ice. They are curvilinear because of the ice's detachment from pebbles and grounding edges. Sublimation rounded the fracture edges and so they scattered sunlight. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/9cf3114f-00ce-49ae-a9e1-53ab2cb6b773/Driveway+Puddle+C.jpg Ice - Puddles Driveway Puddle C: More detail of the fine ring fractures. They appear to have some width but that might really be light reflecting from within the fracture, as commonly seen on big lake fractures when ice is clear. The image is of an area about 15 cm wide. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/54ca65df-9fdd-46cd-aec4-3813ac91bd3f/Puddle+among+rocks.jpg Ice - Puddles Puddle among Rocks: This ice sheet was suspended among rocks and anchored along some edges to ground.

Sub-borders (left of center) formed from melt and vapor had grown in air from the flocs during the previous three days. Border ice with flocs below are frozen to a huge boulder in the distance. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/ffba2328-c1e9-4301-baa1-82e605a356e0/Cover+Photo+for+subcat+Frazil.jpg Ice - Frazil A trench at left covered with a sheet of frazil ice beneath which more frazil caught as water moved in the trench. The foreground shows a removed chunk. The frazil first formed within a steep upstream roadside trench right after a mid-winter thaw. The trench was dry when I photographed it during the New Hampshire thaw of January 19, 2023. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/60f2d672-aeaa-4c4d-bc34-c0727c932415/Blades+Under+a+Surface+Sheet+.jpg Ice - Frazil Blades Under a Surface Sheet: A sheet about 1 mm thick had frozen over a trench but in doing so had incorporated frazil ice. The ice then grew downwards and caught more frazil coming down stream. There are many examples of tiny dendritic growth, such as at the lower left center. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/519891d4-5613-45e6-aae5-03b5991b807e/Blade+Growth+Detail.jpg Ice - Frazil Blade Growth Detail: This is a blade on its side.

During cold snaps the ice contracted, causing stress fractures contoured by (primary) grounding line fractures. Additionally, as the water below evaporated to the ice above, the sheet began to sag of its own weight, causing stress fractures. Between these contours are dozens of faint concentric contours which may be stress-induced slip patterns or additional sag contours. The imaged area was about 70 cm. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/ca816701-c67b-46d2-87c3-f2428f2a5b0e/Rut+ice+B.jpg Ice - Ruts Rut Ice B: A completely covered rut that grew from the water it covered and included blades and dendrites.

Blades first formed in or on the twig, the originally coldest object. The long horizontal blade at left was about 1 m long. The mosaics grew from the blades' sides, in a process known as twinning, as the blades lengthened. Repetitive twinning at ever finer scales formed the mosaics. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/7aa0ea39-745b-4943-87fa-8d2ac0b648ca/Blades+over+leaves.jpg Ice - Ponds Blades Over Leaves: These blades range from 2 to 15 cm long. The greens (lilies), browns and oranges (oaks) are leaves just below the ice. Some blades grow from other blades in a process known as crystal twinning. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/43194bcf-3f37-427f-a661-3b82d6db79db/Cover+photo+for+subcat+Ponds.jpg Ice - Ponds Feathery Blades Growing From Twig Seeds: This telephoto makes these flat growths appear 3D, growing up from the base of the twig.

The evaporated molecules rose above the surface and then froze into hoar crystals that refracted and scattered light of various colors to form this surface hoar bow. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/b91b8eae-54b2-4c64-a8ef-740b1a93fbed/Isolated+sastrugi+in+West+Antarctica.jpg Geology - Glaciers and Ice Sheets Isolated Sastrugi in East Antarctica: The dense snow was undercut by wind to the point where the leading edge into the wind then sagged. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/d8f6deb8-2dc0-4c8c-9109-735a93c7b351/Sastrugi+on+Leverett+Glacier+Antarctica+.jpg Geology - Glaciers and Ice Sheets Sastrugi on Leverett Glacier Antarctica: I took this silvery image high up on the Leverett Glacier near where it originates on the high plateau.

From an airplane on 30 December, they appeared like giant dendrites migrating from a large dark and presumably wet area. To my knowledge, they have yet to be explained. https://www.stevearconephotography.com/spiders-webs-insects daily 0.75 2024-05-21 https://www.stevearconephotography.com/spiders-webs-insects/insects monthly 0.5 2023-10-25 https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/2f2dfa2c-f5be-448b-a230-7dc0c19cb9b7/Another+Common+Water+Strider.jpg Spiders and Webs, and Insects - Insects Common Water Strider: I cannot find a distinct name for this bug. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/76d43d50-47f3-49bd-b23d-e26d3806a4ec/Blackjacket+Wasp.jpg Spiders and Webs, and Insects - Insects Blackjacket Wasp: My guide says this little wasp is common.

Those out-of-focus show colorful pseudobands. The imaged area was about 1.7 cm wide. I find that the colors are caused by selective pigmentary absorption during reflection and transmission for many reasons including no change of color with viewing angle, color consistency in multiple reflections, and black bands suggesting total absorption. Other causes are interference between thread surface and back surface reflections, and speckle from a rough surface of each colored segment. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/2dd2f416-9e83-4d7d-b4b6-74eb3cf47519/Grass+Spider.jpg Spiders and Webs, and Insects - Spiders and Webs Grass Spider: This is the spider that spun the web for my transmission images.

One is the real one and in a full, half-wave transverse oscillation at 500 Hz or multiples thereof, given my shutter speed. The other resulted from a multiple reflection generated within the thread, but offset in direction, like a multiple of a rainbow. Other threads are banded because they are out of focus. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/9d812a09-e7f9-4c97-a800-951348ac0b1f/Vibrating+Grass+Spider+Silk_4000.jpg Spiders and Webs, and Insects - Spiders and Webs Grass Spider Threads #2: Reflected light image of part of a funnel web in my garden.

The visitor appears to be Neospintharus trigonum, a predatory spider that invades other’s webs. It has no common name. It fits every descriptor given for this species, including lack of leg banding. The apparent leg banding is too close to be the normal type seen on spider legs and may indicate the leg construction. https://images.squarespace-cdn.com/content/v1/6501e856f2a6767895900d04/9fd1d30d-6818-4bff-ac4b-7d1b8085920d/2025-23_Water+Strider.jpg Spiders and Webs, and Insects - Spiders and Webs Common water strider: I believe this is the common water strider (Gerris remigis) although I cannot positively identify the markings in the National Audubon Society Field Guide to Insects and Spiders or on any strider I found on line. I photographed it on July 10, 2025, on Chambers Pond, in Chambers Memorial Reserve, West Lebanon, New Hampshire.
