Irregular snow crystal (I) – Subdivided into: Ice particle, rimed particle, broken piece from a crystal, miscellaneous; Germ of snow crystal (G) – Subdivided into: Minute column, germ of skeleton form, minute hexagonal plate, minute stellar crystal, minute assemblage of plates, irregular germ; They documented each with micrographs.

Snowflake was a western lowland gorilla with non-syndromic oculocutaneous albinism. [8] [9] [10] He had poor vision, though tests to determine whether he had a central blind spot did not find one. [11]
Arctic fox, a predator of smaller animals that live beneath the snow. Snow supports a wide variety of animals both on the surface and beneath. Many invertebrates thrive in snow, including spiders, wasps, beetles, snow scorpionflies and springtails. Such arthropods are typically active at temperatures down to −5 °C (23 °F). Invertebrates ...
The hexagonal snowflake, a crystalline formation of ice, has intrigued people throughout history.This is a chronology of interest and research into snowflakes. Artists, philosophers, and scientists have wondered at their shape, recorded them by hand or in photographs, and attempted to recreate hexagonal snowflakes.
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.

In addition to the common name snowflakes, the two Leucojum species are also known as St. Agnes' flower, [5] for patron saint of virgins and gardeners, [5] [6] and snowbells. [7 ...
The snowflakes were too complex to record before they melted, so he attached a bellows camera to a compound microscope and, after much experimentation, photographed his first snowflake on January 15, 1885. [5] He captured more than 5,000 images of crystals. Each crystal was caught on a blackboard and transferred rapidly to a microscope slide.
