Charred Log (Volcano and Lava Fields)
Three metre fallen trunk burnt black: a cracked charcoal surface over a broken end, the branch stubs snapped off short and one side pressed into the ash it fell in.
Walkway Boardwalk Module (Volcano and Lava Fields)
Four metre boardwalk module: a 1.2 m plank deck on steel legs 0.45 m above the ground with a single hand rail, the route a survey team lays across crust too sharp to walk on.
Rockfall Pile (Volcano and Lava Fields)
Two and a half metre pile of fallen rock: angular basalt blocks heaped as they came off a face, the big ones at the bottom and the fines washed into the gaps.
Boulder Set (Volcano and Lava Fields)
Three separate volcanic boulders on one base, from 0.8 m to 1.6 m, weathered grey outside and dusted with ash, for breaking up open ground.
Pumice Heap (Volcano and Lava Fields)
Two metre heap of pumice: pale frothy blocks so full of gas bubbles they would float, drifted together in a hollow with a fine gravel of the same rock around them.
Lava Bomb Impact Crater (Volcano and Lava Fields)
Three metre impact pit in soft ash with the bomb still sitting in the bottom of it: a raised rim of thrown material, radial splash rays and the block half buried at the centre.
Volcanic Bomb, Large (Volcano and Lava Fields)
Two metre bomb: a block too big to have chilled in flight, landed soft and flattened on one side, its upper surface a crust of welded clots over a cracked scoria body.
Ash Drift (Volcano and Lava Fields)
Two and a half metre drift of wind piled ash, steep on the lee side and feathering out on the windward one, with the tips of buried blocks showing through the crest.
Volcanic Bomb, Small (Volcano and Lava Fields)
Half metre spindle bomb: a clot of lava spun into a tapered shape in the air and cracked along its length where the skin chilled before the inside stopped moving.
Volcanic Bomb, Medium (Volcano and Lava Fields)
One metre breadcrust bomb: a rounded block of scoria whose chilled crust has split into plates over an expanding core, with the glow of the inside showing in the splits.
Obsidian Flow Slab (Volcano and Lava Fields)
Three metre block of an obsidian flow: a mound of black volcanic glass in tilted slabs with sharp conchoidal edges, the shattered blocks at its foot the ones that broke off as it cooled.
Lava Fountain Plate (Volcano and Lava Fields)
Fountaining vent modelled as geometry: a 2.6 m spatter rim round a glowing throat with nine molten jets rising to 2.8 m, frozen as solid emissive shapes rather than an effect.
Scoria Cone (Volcano and Lava Fields)
Small cinder cone eight metres across and 2.8 m high with a breached crater at the top, built of loose red brown scoria with a bomb scatter down the outer slope.
Geyser Cone (Volcano and Lava Fields)
One and a half metre geysirite cone built layer by layer round a geyser throat, pale mineral crust over a rocky core with a wet dark vent at the top and a runoff apron at the foot.
Hot Spring Pool Edge (Volcano and Lava Fields)
Four metre hot spring: a still pool inside four stepped sinter terraces, the rim built up in pale mineral ledges and the water a flat plate set below them.
Mud Pot (Volcano and Lava Fields)
Two and a half metre pool of boiling grey mud in a splashed rim of the same mud, with burst bubble domes frozen on the surface and a spatter apron of thrown mud round the outside.
Fumarole Vent With Sulphur Crust (Volcano and Lava Fields)
Gas vent in cooled ground: a 1.2 m collar of rock stained and crusted with bright yellow sulphur round a dark throat, the deposit thickest at the lip where the gas condenses.
Steam Vent Plate (Volcano and Lava Fields)
Two metre plate of ground venting steam: bleached cracked crust round three open holes, ringed with pale mineral deposit and the dark wet stain a hot vent leaves.
Sulphur Deposit Patch (Volcano and Lava Fields)
Two metre patch of sulphur encrusted ground: a bright yellow crust over bleached rock, cracked into plates and studded with small needle clusters at the hot spots.
Hornito (Volcano and Lava Fields)
One and a half metre chimney of welded lava clots built over a skylight in a tube roof, leaning slightly, hollow and glowing at the throat.
Spatter Rampart (Volcano and Lava Fields)
Three metre wall of welded spatter thrown up along one side of a fissure, a low irregular rampart of fused lumps standing on a glassy apron.
Basalt Column Cluster (Volcano and Lava Fields)
Cluster of seventeen hexagonal basalt columns to 2.8 m, the cooling joints of a thick flow standing where the softer rock around them has weathered away, with broken column stubs at the foot.
Lava Tube Mouth (Volcano and Lava Fields)
The opening of a lava tube in a slope face: a 2.7 m arch of layered basalt coming out of a rocky mound, over a floor of frozen flow, with a fallen block apron outside and the passage dark a few metres in.
Collapsed Tube Roof (Volcano and Lava Fields)
Four metre tile where the roof of a lava tube has fallen in: a ragged 2.6 m skylight rimmed with tilted slabs, the fallen roof piled on the tube floor a metre below and daylight reaching the rubble.
