Actually, the Big Rock in Okotoks, Alberta pictured on that wikipedia article isn't far from here, only about a 2hrs drive. There's another one 40 minutes away, called the Glenwood erratic, both are popular for bouldering, I've climbed on both. I vote for calling the released clast an, "emancipated clast." | |

In this case, the original sandstone acts like a carrier which then releases the boulders after. It reminds me of a glacial boulder which is sometimes called a "glacial erratic". | |

| Feb 29, 2016 at 21:29 | comment | added | Gimelist | @ShemSeger I'm not a sure there is a term for "rocks that used to be lithoclasts but are now just boulders sitting there". If there is, it's mostly likely an obscure term that no one knows unless you're an extremely old professor that insists on using excess jargon. | |
| Feb 29, 2016 at 13:28 | comment | added | ShemSeger | Then what do you refer to the stones as after they've been freed from the sandstone? There are large stones out there just laying in the sand like eratics, but they are there because they eroded out of the hoodoo. | |
