The photo was taken in a lava cave. We can see the black lava rock of the cave that solidified when the lava flowed through. The cave disappears into the darkness. ©AW

Dark and cold, the moisture is visible in the beam of the flashlight.

A swirl of grey lava rock leads into the red, shadowy glow of a lava tube illuminated by lights along its path.

Lava Tube #2, Snow Canyon State Park
Shot from inside Lava Tube #2 near golden hour, as warm light poured in from the entrance. Just as I took the photo, a couple entered with a flashlight, casting that blue glow across the rocks.

Good morning/good night, depend where you live on this world🌎
Here is a photo from the amazing view on old volcanos on Lanzerote before going to the old lavatube.

Come hither.... if you dare... and explore the darkness that is the bowels of Mother Nature.

A lava tube cave at night. There are red walls with what looks like red guts hanging from the ceiling over the darkness of the path ahead, which is shown by the blackness of an arch.

Inside a lava tube in Hawaii at nighttime. There is a black arch in the middle you can walk through if you dare, surrounded by what looks like bright red blood and guts of previous people who tried (not really) dripping around it. It's a scary looking scene, though.

Seeking light.

Sometimes there is a light in the tunnel. It doesn't always mean that it's an easy way out of the darkness. Still, there is beauty and joy in finding light in the darkness. Learning to surrender to it is the hardest part.

Challenge: #Underneath!
Far below the surface, the silence embraces you.
The light and shadows, are like the stone.
#BlueSkyArtShow #Underground #Cave #LavaTube #LavaBedsNationalMonument #Spelunking #📷
A greyscale photo of an underground scene. I have a bright light source pointing into the cave ahead of me. I am silhouetted strongly by the light just right of center. The rock wall in front of me is brightly lit. Ahead where the light is pointed, and to my left is a rubble pile of stone, with strong shadows behind it. Above the pile, the stone roof of the cave is seen, and can be followed toward the top of the image. The foreground is very dimly lit by another light source somewhere behind to the far right.

"The Meatball" #RockinTuesday
This lava tube feature is a stone wedged in a narrow channel overhead, and fused there. It was named by a scout troop long ago, in the cave that bears their youth troop name, "Ape Cave".
#ApeCave #LavaTube #cave #hiking #EastCoastKin #BlueSkyArtShow #TheFloorIsLava #📷
A photo from inside an underground lava tube. A formation caused by a lava flow that hardened on the surface, then drained, leaving a stone tube that can be explored. Sometimes the structures underground can be complex, or quirky. Here, people are walking through the lava tube in silhouette from their headlamps, under a narrow channel where a flow of lava left the walls more narrow, then drained further down. A stone of lava rolled into place and wedged itself in the narrow part overhead, fusing in place. A small spot light highlights the feature. The feature was named "The Meatball" by a scout troop that explored this very long lava tube many decades ago on the slopes of Mount Saint Helens of Washington State, US. The lava tube is banned for the youth scout troop, The Apes, thus "Ape Cave". The 1980 eruption of the volcanic mountain did not create this lava tube. It is far far older than that.

Why / how come there are TWO red glowing points visible near the ground here ? Also visible in this black-and-white photo

Lavatube or 2nd eruption site ?

For #RockinTuesday I'm returning to my stash of #cave photos! Here's part of a massive lava tube with a bonus permanent ice deposit at the bottom (not featured). Skull Ice Cave!

At this point the railing is freezing to touch.
A black and white photo of a view deep inside a complex landscape inside a huge lava tube. In the immediate foreground is part of a system of metal railings, platforms, and ladders, enabling visitors to safely descend into the cave. To the railing's right is an exposure of solid lava rock that rapidly descend out of sight. The area above the rock is unlit by the hand light, and is pitch black. The rest of the area visible by the lamp light is a circular lit area that occupies much of the middle, and left side of the photo. The system of metal railings and ladders is seen to turn to gain access to a gaping pit in the floor, which a metal stairway drops through. More rock wall can be seen as it descends viewed through the pit. The far side of the pit is a narrow ledge of rock that looks like a bridge between the pit and another circular opening in the cave that reveals blackness beyond.
