The colorful Badlands

with 14 comments

Okay, so I’ve been holding out on you when it comes to the best color I saw in the Badlands of South Dakota on May 31st.

Well-travelled Austin photographer Rick Capozza explained the colors to me: “White layers are volcanic ash or tuff as they call it in Big Bend. Tan and gray are sand and gravel. Red and orange are iron oxide deposits, primarily ferric oxide. Purple shale colors represent manganese deposits and yellow layers are ferrous sulfate.”

Six years

with 49 comments

Six years ago today I uploaded the first post of now almost 2300 in Portraits of Wildflowers. You might say that tentative entry was like the little fern shown above getting a foothold in the vertical strata along the trail we trekked to New Zealand’s Franz Josef Glacier on February 20th this year.

Those strata, which hadn’t always gotten turned 90°, proved so visually appealing that I took many photographs of them. Below is another one. The pink in both cases is from small lichens. Call these formations waterfalls in stone and you’ll have come up with an apt metaphor.

Volcanoes in Austin

When most people think of Austin they don’t think of volcanoes. Nevertheless, this region was once volcanically active. Whether the sinuous brown strata in a cliff along Onion Creek in far southeast Austin in this picture from July 19 are igneous, I’m not sure, but an expanse of rock a few minutes’ walk away from this spot clearly suggests an origin as congealed flows of lava.
