Ecydhh2118

 

Hypothesis

 

A shows two tubes coming out of a hollow hill with a settled roof. B shows this connecting through a collapsed roof to another hollow hill at 4 o’clock. At 8 o’clock may be another tube.  Shows a collapsed segment of the hill at 1 o’clock and a second hollow hill at 5 o’clock.

 

 

Ecydhh2118a

 

Hypothesis

 

An approximate parabola is shown.

 

 

Ecydhh2119

 

Hypothesis

 

A, B, and C show a tube connecting two hollow hills. A at 8 o’clock shows where the roof has collapsed. B shows how a hill surrounding a crater connects to this tube. C shows a dark rectangular segment at 8 o’clock connecting to the tube and the main dome at 4 o’clock.

 

 

Ecydt2120

 

Hypothesis

 

A shows two tubes connected, B shows a tube expanding into a triangle before connecting to a hollow hill surrounding a crater at D. C from 8 to 3 o’clock shows how this tube connects to another crater, it forks into a second tube going into a hill from 10 to 2 o’clock.

 

 

Ecydt2122a

 

Hypothesis

 

A, B, and C show excavation dams cut into the crater floor.

 

 

Ecydt2122a2

 

Hypothesis

 

Two parabolas are shown.

 

 

Ecydt2122b

 

Hypothesis

 

A shows an artificial looking bend in the side of the dam at 8 o’clock, two other dams at 4 and 6 o’clock. B shows another dam with an overflow dam at 6 o’clock second leg.

 

 

Ecydt2122b2

 

Hypothesis

 

Three parabolas are shown.

 

 

Ecydt2122c

 

Hypothesis

 

A and B show how the dam wall is degrading, A at 8 o’clock is in good condition, at 5 and 7 o’clock the cement edge of the dam wall has been undermined perhaps from water overflows in the past. B shows a double wall from 2 to 7 o’clock as if the central dam wall has eroded away or fallen off. The wall may have been full of gravel with an inner and outer skin of cement, when the top breaks then the gravel would fall out leaving a hollow. At 7 and 8 o’clock first and second legs there is an undermining of the wall.

 

 

Ecydt2122c2

 

Hypothesis

 

Two parabolas are shown.

 

 

Ecydt2122d

 

Hypothesis

 

A shows regular layers, perhaps how these formations are constructed. B at 8 o’clock shows these layers go deep into the rock to the crater wall. B at 6 o’clock shows the smooth dam wall, at 4 o’clock the dam wall top is falling apart. C at 6 o’clock shows the dam is highly eroded as is the arch between B and C unlike at A. At C at 2 o’clock the dam wall also shows some layers.

 

 

Ecydt2122d2

 

Hypothesis

 

A parabola is shown. C was probably also a parabola.

 

 

Ecydt2122e

 

Hypothesis

 

A at 8 o’clock would also be a small parabola, at 5 o’clock is an inner and outer parabola. At 2 o’clock the dam wall is eroded but still shows a clear edge to it. B is also eroded, this may be more from the material in the crater than flaws in the construction.

 

 

Ecydt2122e2

 

Hypothesis

 

An inner and outer parabola is shown.

 

 

Ecydt2122f

 

Hypothesis

 

This may be a collapsed tube, a dam, or canal, A appears to be dams. B shows this deep channel and how the top of the wall is eroded here. C shows the wall has cracks in it perhaps eroding like B but less advanced. D at 6 o’clock shows the top of the wall is flattened, at 4 o’clock it may have pillars in it.

 

 

Ecydd2124

 

Hypothesis

 

A, B, and C show excavation dams, this material may have been brought up from the bottom of the crater. Alternatively dunes and other loose material could have been pushed into the crater, but this would show signs around the top of the crater.

 

 

Ecydd2124a

 

Hypothesis

 

Two parabolas are shown.

 

 

Ecydt2125

 

Hypothesis

 

A and B show a wall or tube connecting a crater and a hollow hill. A shows a connection to the crater at 8 o’clock and a connection to another altered crater at 5 o’clock. D at 11 o’clock shows this connection to the hill, at 1 o’clock the hill is collapsing. C shows a connecting tube approximately at right angles, this may go underground. E shows a smaller tube connecting to a crater.

 

 

Ecydt2125a

 

Hypothesis

 

The two tubes are quite straight, with an angle of 90° between them.

 

 

Ecydt2126

 

Hypothesis

 

A and B show tubes between craters and hills. C shows another tube going to a crater. D from 7 to 11 o’clock shows a thicker tube connecting to a crater, a smaller tube at 4 o’clock connects to another crater. E and F show more tubes.

 

 

Ecydhh2127

 

Hypothesis

 

A shows a wavy tube at 10 o’clock, at 4 o’clock is a wall or dam surrounding part of the hollow hill continuing down to B. C shows a collapsed segment of the hill, D shows a cavity on the roof. E shows another collapsed segment at 8 o’clock, this continues up to 11 o’clock. At 2 o’clock is a wall perhaps a pit dam.

 

 

Ecydhh2127a

 

Hypothesis

 

This shows a parabola forming part of the hollow hill. Also the lines show how straight parts of the formation are.

 

 

This next section shows formations in and near Isidis Crater.

 

Ist2128

 

Hypothesis

 

Many tubes are shown here connecting to craters. F shows two of these, it crosses a tube at C going up to D.

 

 

Ist2128a

 

Hypothesis

 

This shows how straight some of the tubes are.

 

 

Ist2131

 

Hypothesis

 

A shows a tube connecting craters, it goes up to B around a crater then over to C and D into a hill.

 

 

Ist2142

 

Hypothesis

 

A and B show tubes connecting many hills. These continue up to C and then down to D and E. 13 out of 14 hills are connected by tubes here.

 

 

Ishh2143

 

Hypothesis

 

A shows a wavy tube as if it was broken by a flood or high winds. This connects to the hill at 2 o’clock, segments have collapsed such as at 4 o’clock. B shows other collapsed segments of this hill at 8 and 10 o’clock. At 11 o’clock first leg there is a tube coming out of the hill, at the second leg there is a collapse in the roof. C shows another tube coming out of the hill.

 

 

Ist2200

 

Hypothesis

 

A shows some straighter tubes, B at 1 o’clock shows how the tube has eroded into a series of arches or pillars. It connects to other tubes at 7, 8, and 11 o’clock. A triangle is shown at 4 o’clock, probably a collapsed hollow hill. Some of the other hills in this area are triangular, there may be an entrance at C at 10 o’clock. At 2 o’clock the tube has collapsed into a much wider shape or this was another hollow hill. D shows a wavy tube, this has an entrance between it and the tube at E or it rolled to become disconnected from it.

 

 

Ist2206

 

Hypothesis

 

A shows tubes connecting craters or pit dams at 11 and 12 o’clock, also at 4 and 5 o’clock. At 2 o’clock these tubes connect together. At B at 10 o’clock there may be a small segment of tube that has become disconnected. This continues on through another pit dam at 11 o’clock into a hill at 1 o’clock then a second hill at 2 o’clock. C shows a straight tube from a crater to a hollow hill and beyond it.

 

 

Ist2206a

 

Hypothesis

 

This shows how straight some of the tubes are.
