@JanPV Beautiful! Not my specialist area, but I think that these are hackle or plumose marks. Most rocks are not homogenous, so when fractures form, they propagate in rather complex ways. The ones in you photo look as though they might be associated with finer-grained (siltier, or more shaly) beds in the rock, and might have propogated downwards. I'm not a structural geologist so this is all a bit vague. @allochthonous can probably say more, and more reliably! 😁 #StructuralGeology

[as a geologist and an adventure rider – and a Colorado resident that loves history - I have travelled all over this area; first photo is mine, my motorcycle under the Apishapa Arch in Aguilar, Colorado, a 1930s Civilian Conservation Corps project through a volcanic dyke, ‘coincidentally’ providing better access to land that a senator had purchased up around Cuchara and Cordova Passes]

Today: #VolcanoThursday meets #StructuralGeology. Last year during #hedgewatch on #Iceland we found this #slickenline in #lava from the 1st 2023 #eruption at #Fagradalsfjall. The scratch originated when a block of solidified lava was pushed over softer lava

....... Fig 3 #Slickenlines are impawtent if you find them on #faultplanes because they can tell you in which direction the #rocks moved🙀 This example is from #Crete
