Hellhole is closed to the public, all caving is strictly prohibited. It is only open to members of the Germany Valley Karst Survey who are exploring and surveying the cave, and then only during the summer months due to endangered bats that use the cave to hibernate.
This rather odd cloud formation caught my eye while I was driving out of Kooralbyn. I didn't have my Nikon with me, so I got the little Canon Powershot out - still takes a rather good photo!

20 (if I counted right) P-51s flying an incredibly formation over GML2007.
The sound was just amazing
Banded iron-formation in the Precambrian of Ontario, Canada.
This is an exposure of glacially eroded, Archean-aged, folded, magnetite-rich banded iron formation (BIF). An adjacent roadcut shows these BIFs perched atop basement rocks. Occasional patches of shiny glacial polish are present.
I'm not absolutely sure about the formal stratigraphic name of this unit at this site, but it appears to be the Michipicoten Iron-Formation (Neoarchean, 2.696 to 2.749 billion years old).
The exposure is anthropogenic - the original vegetation and soil was stripped away after visible gold was discovered in a shear zone/fault zone nearby. The inactive Ranson Gold Mine occurs near here, which exploited the same gold occurrence that was found in the stripped area. The basement rocks below the BIFs are part of the Bridget Lake Stock, which consists of “quartz feldspar porphyry”. The Bridget Lake Stock is supposedly the source of the gold mineralization.
Locality: Antoine Lake West Outcrop - glacially eroded exposure on the southern side of Route 17, just west of Antoine Lake, southeast of Bridget Lake, south-southwest of the town of Wawa, Michipicoten Greenstone Belt, Ontario, southeastern Canada (47° 53’ 44.43” North latitude, 84° 50’ 46.62” West longitude)

Wupatki National Monument preserves a collection of Puebloan ruins dating from about the 12th century. The ruins themselves lie on a transition zone between the San Francisco Volcanic Field and the largely sedimentary Painted Desert. Water has shaped this landscape, like so many others in Arizona, into something completely unique. Patience and time has created a perfect network of washes and drainages, and also some very unique "potholes" in the sandstone, such as those above.
