an assortment of brightly-coloured algae reflect in the steam rolling off a large hot spring.

appearing as a beautiful iridescent wing from a magical creature, this is actually a small portion of a single grain of black sand. we were exploring a small clump of sand for a good shot, and noticed a tiny colourful spot sparkling out from one of the grains of lava rock. zooming in much more, we discovered this 'wing' shape measuring 0.0058 inches long (equivalent to the thickness of a sheet of paper). the entire grain of sand at this level of magnification, would fill 20 of these photos.

this is a closeup shot of a copper snake chain necklace. the islands of gold are parts of corroded copper links that are kept bright by constantly rubbing against the skin. the aqua river is the remaining part of the copper that goes down into valleys between chain links where the corrosion has gone untouched and turned a beautiful blue-green. the chain of this necklace measures 0.045 of an inch in diameter and this photo captures an area equivalent to the thickness of a credit card.

This is a highly concentrated salt lake in eastern California that is known for its unique calcareous rock formations (tufas). These structures range from a couple feet to perhaps 15 feet tall and are quite rigid. Most of these structures form on the ground near the shore, but I really enjoyed this grouping when surrounded by water. Plus, the winds coming over a nearby mountain range, produce complex clouds rolling over this area and are usually quite interesting and often stormy in appearance.

looking quite similar to an xmas tree with ornaments and tinsel, this is actually a photograph of a hostile invasion possibly taking place in your own backyard. if you see a plant with a white or light-gray powdery substance on the top-side of its leaves, it is probably an invasion of the 'White Powdery Mildew Fungi'. many different types of these spores spread with the wind, rain, birds, and even the feet of insects, and when the right type of spore lands on a suitable plant, it quickly takes hold by rooting into the plant. it then steals nutrition from the plant to grow an outbreak of thread-like structures over the surface (seen as white rice-like chains in this photo) which eventually block the plant's photosynthesis process and kills it. when the mildew fungus is sufficiently mature, it develops new sets of spores (inside the brown raisin-like containers) to travel in the wind and repeat the cycle. each of the brown spore-sacks measure about 0.0014 inches in diameter which is the thickness of kitchen aluminum foil.
