On the Cataract Trail (II)

Another cascade from the Cataract Trail near Mt Tamalpais:


Ginkgo leaves

Ginkgo trees sometimes dump all of their leaves at the same time – here’s an image of the scatter of leaves at the base of a tree:

On the Cataract Trail

A waterfall from a trail on the west side of Mt Tamalpais in Marin County: _MG_5046-cascade-trail There are dozens of cascades along the trail, which is quite steep. Despite the lack of rain there was a decent flow in the creek.

Crystal stars

Star-shaped crystals form on stream ice when it gets very cold – in the single digits F. The smaller shapes are stars or crosses, but some forms are masses of pointed crystals. The snow at the edge of a stream can form dense mats of these crystals, and the icy surface can have clusters of starry crystals. Here are a few crystal islands on dark stream ice:


Crystal shapes

Frost crystals grow in different shapes, depending in part on the temperature. On one morning, I found the snowflake-like hexagonal plates you see in one of these images. All of the leaves around this one were covered with them. On another morning, I found rod-like frost crystals. When you get close enough, you can see that the rods are pipes of ice, hollow inside.

This sort of image – frost on leaves scattered in the ground – is the sort of thing I take in late fall. In early January when I took these, the ground was still bare, and the leaf litter was still visible. Hard to imagine that now, with three or four feet of snow on the ground.

Plectranthus ‘Mona Lavender’

Field tree

An isolated oak in a foggy California field – there’s a bit of sun shining on a few of the rows of whatever was coming up:

_MG_4770-2-tree From a visit in California a couple weeks back. I like the look of this field better than the 30 inches of snow on the ground here in Massachusetts…

For Maryrose.

Crystals and a leaf

Frost crystals that formed under a leaf on frozen stream:


Taken on a really cold (0 degrees F) morning. The fern-like crystals on the right side of the leaf only form when it gets very cold, down in the single digits. I’ve seen crystals around a leaf like this, but the holes in the leaf and the profusion of crystals give this an unusual look.
