Prhh1068d

 

Hypothesis

 

A may be another pit dam, the smooth floor is like cement. The terrain outside the dam is much rougher. B shows a smooth floor and a wall, around C is a nearly rectangular walled area.

 

 

Prhh1068e

 

Hypothesis

 

Similar to the rooms and walls in Cymmeria, the only example of this in Protonilus. A shows some rooms and perhaps an interior support if there was once a roof on this. B shows more rooms, all are around the same size. C at 7 o’clock may contain rooms, at 8 o’clock there may be ceiling material still covering some of them. D may also be ceiling material, at 6 o’clock more rooms are exposed.

 

 

Prhh1068e2

 

Hypothesis

 

The lines show how straight the walls are.

 

 

Prhh1069a2

 

Hypothesis

 

A is a parabolic wall, B appears to be another pit dam with a smooth cement floor.

 

 

Prhh1069a2a

 

Hypothesis

 

Two parabolas are shown.

 

 

Prhh1069b2

 

Hypothesis

 

An unusual formation, the smooth surface may indicate it is cement. It appears to be concave so would have held water like a dam.

 


Prhh1069b2a

 

Hypothesis

 

One side of it is close to a parabola. The bottom side appears to be broken and irregular.

 

 

Held1072

 

Hypothesis

 

The next images are in Hellas Crater. A and B are dams similar to those in craters in Cymmeria. C shows the dam walls, at 7 o’clock one double wall with a hollow inside it extends further up to collect more water.

 

 

Held1072a1

 

Hypothesis

 

The dams form two parabolas.

 

 

Held1072a

 

Hypothesis

 

A shows another dam, the ridges at B and C may have slowed the water flow, or collected water as small dams. These pockets of water may have been used for crops like rice paddies on hills in Asia. D shows a smooth cement like layer degrading to exposed the rougher ground under it.

 

 

Held1072

 

Hypothesis

 

A parabola is shown.

 

 

Held1072c

 

Hypothesis

 

A is smooth like cement creating a dam at 2 o’clock, at 10 and 11 o’clock there are possible interior supports like pillars exposed in the cement wall. B shows a smoother cement funnel to direct water to another dam.

 

 

Held1072c2

 

Hypothesis

 

The dam has a parabolic shape.

 

 

Held1072d

 

Hypothesis

 

These may also be conduits for water, A shows how smooth the walls are with vertical supports exposed to increase their strength. B shows more smooth curves like cement. C shows transverse ridges in the hollow as if strengthening it like arches.

 

 

Held1072d2

 

Hypothesis

 

Three parabolas are shown, the knob is close to two parabolas intersecting to increase its strength.

 

 

Held1073a2

 

Hypothesis

 

Another area in this crater is also parabolic as shown, A shows the intersection between a smooth surface like cement and the rougher terrain inside the parabola. B shows ripples perhaps from cold flow as the rock moves down like a liquid over time. They may also have acted like arches strengthening the hollows. C shows rougher terrain above the smoother hollows as does D. The vertical grooves around C may have increased the strength of the knob as interior supports. C at 6 o’clock looks like a small dam as does B at 4 o’clock.

 

 

Held1073c

 

Hypothesis

 

A at 7 and 8 o’clock looks to be a small dam with a ravine feeding at 4 o’clock. A shows an entrance perhaps going under the wall at C at 10 and 11 o’clock. There appears to be a depression on the other side implying a water tunnel. At 7 o’clock a layer is degrading like cement, also at B at 12 o’clock.

 

 

Held1073c2

 

Hypothesis

 

The wall forms a parabola with the water tunnel at the apex.

 

 

Held1074

 

Hypothesis

 

These dams have dam shapes like parabolas under them, as if to reinforce their strength.

 

 

Held1074a

 

Hypothesis

 

These form 4 parabolas.

 

 

Held1084d

 

Hypothesis

 

This shows a complex series of dams and funnels, A shows a smoother water conduit probably made of cement. B shows two water funnels, C shows a dam at 2 o’clock, also one at 4 and 6 o’clock. These are probably all parabolas. D shows a parabolic arch at 1 o’clock and more funnels at 6 and 7 o’clock.

 

 

Held1084d2

 

Hypothesis

 

Two parabolas are shown.

 

 

Held1084e

 

Hypothesis

 

Many of these curves would also be parabolic to increase their strength. A shows a smooth water conduit with rough terrain to its right. B shows a water conduit which may come from a water tunnel as there is no funnel above it. C shows more water conduits probably covered in cement. D shows water conduits going down to the dam at 7 o’clock. E shows another smooth wall directing water downwards.

 

 

Held1084e2

 

Hypothesis

 

This shows the clearest parabola though there would be many more.

 

 

Held1084f

 

Hypothesis

 

A shows a smoother water conduit like cement, B would be a parabolic arch between 2 and 9 o’clock. C shows another dam and water conduit. D shows a small dam.

 

 

Held1084f2

 

Hypothesis

 

This shows 7 parabolas making up the dams and water conduits.

 

 

Held1084g

 

Hypothesis

 

A shows a water funnel at 8 o’clock, perhaps a small dam bordered at 4 o’clock. B shows a dam and the water conduit that fed it. C shows an unusual hole, perhaps an entrance to a habitat. D may be another small dam.

 

 

Held1084g2

 

Hypothesis

 

The dam forms a parabola.

 

 

Held1087

 

Hypothesis

 

A shows a dam with another dam under it to catch the overflow. B shows more dams nested under each other as does C.

 

 

Held1087a

 

Hypothesis

 

Two parabolas are shown.
