What kind evidence would you expect?
That has already been suggested. There would need to be a single band of flood-type deposits found all around the world, not interrupted by formations that are incompatible with flood conditions.
I find it interesting that you asked only about evidence that is missing. Are you not curious at all about the second type of evidence?
"2. Evidence which has been found that could not exist if a global flood had occurred."
Limestone,
Quartz is often formed often along with other stones, such as Pumice, Rhyolite, and Granite; These are formed when molten rock is cooled, or solidifies. During the floos we would see many volcanic eruptions.
Shale is fromed from previously existing rocks that were eroded, and redeposited elsewhere, which would happen during the flood.
And
chalk
The basic reason I mentioned different types of rock is that they require different environments in which to form. But a global flood basically offers one type of environment. So how can you get rocks as different as quartz and shale from the same flood?
Also, each of these, as well as many I did not name, provide difficulties for a global flood theory.
Consider shale. You may have done one of those experiments where you put gravels and sands of different diameters in a jar, fill it with water, seal it, shake it vigourously, and then let the sediments settle to the bottom. If you have, you know that the larger, heavier particles settle earliest and lowest, with smaller, lighter particles settling last and highest.
You will also know that the large, heavy particles settle almost immediately, but the lighter particles take much longer to settle. The very lightest will remain in the water column for hours making it cloudy.
It is these very light particles that shale is formed from. In order for shale to form at all, the water in which it is forming must be very still for a long time to allow these particles to settle as sediment.
Chalk is also made from similarly very fine particles of calcium carbonate. A chalk particle, 2 microns in radius, takes about 80 days to fall through only 300 feet of very still water. So AiG's coccolith blooms are not a sufficient answer. Even if they occurred, that only supplies a source for the chalk particles. But before you get chalk formation, the foraminifera and coccoliths have to complete their life-cycle and die, and their skeletal material be broken down into chalk particles and the particles themselves would have to sink to the ocean bottom. And only then under the intense weight and pressure of water and more sediment could it begin to lithify. And all this time, the water has to be extremely still. Any turbulence would simply pick up the chalk particles and whirl them into the ocean currents to begin their long slow descent to the bottom again somewhere else.
The big problem with both limestone and quartz is heat.
Consider the Ordovician limestone formations in North Dakota.
These can not be the flood deposits for a reason of heat. Each gram of carbonate gives off about 1207 kilocalories per mole (Whittier et al, 1992, p. 576). Since the density of the carbonate is around 2.5 g/cc this means that there are 2.2 x 106 moles of carbonate deposited over each meter. Multiply this by 1,207,000 joules per mole and divide by the solar constant and you find that to deposit these beds in one year requires that the energy emitted by each meter squared would be 278 times that received by the sun. Such energies would fry everybody and everything.

You attribute quartz to volcanoes. But what is the basis for claiming "many volcanic eruptions" during the flood? Scripture mentions no volcanoes. Nor can I think of any reason why a global flood would trigger volcanoes.
What are volcanoes needed for?
And how many volcanoes would there be? Would they occur under water or above water? Would they occur at the beginning of the flood only or throughout the whole year?
What evidence would you expect to remain as a consequence of these volcanoes today? Has this evidence been found?
How can the existence of many volcanoes be reconciled with the extremely still waters needed for shale and chalk formation?
How can the existence of many volcanoes be reconciled with the survival of life? Volcanoes generate heat. Many volcanoes generate a lot of heat. I've seen estimates of the catastrophic type flood that included many volcanoes and continental breakup and that sort of thing raising the atmospheric temperature into the thousands of degrees (both Centigrade and Fahrenheit). Under such temperatures, you wouldn't have a flood for very long, because the oceans would boil off into steam. Of course, you wouldn't have life very long either. Not even in the Ark.
And we haven't even begun to talk about rocks that cannot form in water, rocks that show paleosoils, or rocks, including shales that show burrows and other trace fossils that are all incompatible with a global flood.
What evidence do you think indicates they were not?
In many places marine environments are intersperced with terrestrial environments, like a club sandwich of several layers. The terrestrial environments show an established ecology with vegetation growing. Fossils are found in both the marine and terrestrial environments. Different fossils, suited to the environment. You can't have all of these burials occurring at the same time, because you can't have the area being water-covered and dry land at the same time.
What would provide quick and complete burial in a calm, shallow sea?
Depends on the size of the organism you are speaking about. For smaller organisms the natural bio-turbidity of larger organisms feeding on the bottom would kick up enough mud to envelope them while most of the water remained calm. You would also get relatively rapid sedimentation at the mouths of rivers and creeks emptying into the sea. And now and again you could get an underwater landslide.
THe problem I see with that is that you cannot prove that all of the footprints were made in mud.
I never suggested they were. That was just an example of a kind of print that can last for quite awhile.
If they were not, than I should think the light dust would have to be propelled by some source that would put it into the imprint; likely wind.
Not necessarily. You can have a lot of dust settling even with virtually no wind. Have you ever had the opportunity, perhaps at camp, to see beams of light shining into a darkened room or tent, or shady part of a woodland? If so, you may have noted the dust motes highlighted by the sunshine. Sooner or later they all fall to the ground, or onto the furniture, which is why you have to dust or vaccum even when a room is not being used.
I read something interesting a while back. It was the fossil of a crab, with a small trail of it's footprints leading to it. Obviously the crab was buried quickly--it was not decayed at all. This means that the footprints were also covered quickly.
Exactly. And then fossilized along with the crab. Remember burial is necessary to fossilization, but its not the same thing as fossilization. The fossilization is a slow process that occurs after the burial.
