Most ancient creeks may have been torn up by continental glaciers or even alpine glaciers.

it depends !!! And this is a great topic !!! and very roomy !!!

Would the vegetation be more dense or less dense? Why?  General less dense !!! Flowers don't just need water !!!
On one of these channels I saw :  a herd of cows - and of course plants - generally these plants give depleted food to cows - so cows give  less milk and the meat tastes worse - farm crops - cultivation difficult conditions - This does not mean, however, that the flowers must be less green !!! - but sometimes they are - and no !!!
 Also depends on the deposit - climate - From the satellite you can - but not always - rely on plants -
but it's better to look at the terrain - and see plants !!! - You won't see it from the satellite - not everything -
1-2 percent !!! And not only the old channels you will see  -thanks to plants  !!!

ps - my English is not perfect - sorry for that .

Geochemical prospecting is an interesting subject. I know a guy that uses this method and is quite successful with it.
It does take some equipment and learning though.

This is from Action Mining Supply.

The info and supplies are on page 42 of their online catalog. Prices good through June 2019 41
Geochemical Supplies
When looking for gold, don't took for gold,
look for geochemicals
Basic Theory
  The presence of geochemical haloes has been known and used for 59 years by many mining companies. All deposits of precious metals have associated geochemicals. Precious metals do not exist in deposits without geochemicals that are to some extent, water soluble. These geochemicals always wick their way out through solid rock and dirt over thousands of years. Such chemicals are detectable by our Geochemical Meter.
So when looking for gold, don't look for gold, look for geochemicals. The geochemicals spread out several hundred feet while the gold stays hidden. Most of the gold at the surface has already been located. Now the Geochemical Meter gives independent prospectors and miners higher technology for locating the 85% to 90% of gold that has not yet been found because it is beneath the ground surface.
In the past few years several of the larger mining companies have become discouraged with geochemical prospecting. They have made the mistake of looking for acid soluble geochemicals. Unfortunately, acid soluble geochemicals exist everywhere, and water soluble geochemicals exist only around mineralized veins and placers. Thus looking for acid soluble geochemicals can be very confusing and unproductive. When properly carried out, geochemical exploration is the best modern method available, regardless of price, when prospecting for precious metals.
What You Can Use It For
Preliminary Assays - If you want to know whether you should have a rock assayed or not, use this meter. A high reading should be assayed and a low reading indicates that it will be useless to assay the rock. The
instruction manual gives details.
Placer Prospecting and Evaluation - All placers have geochemical haloes. Does a placer exist in the area? The ground will read high in the placer area and will gradually taper off as you leave the placer. High readings in the dirt indicate a 98% chance of a placer if you use the meter correctly.
Prospecting for Hard Rock Gold Veins - All mineralized veins have geochemical haloes. These geochemicals wick their way to the surface over the hundreds of years. They even go through solid rock. You can use them to detect mineralized veins hundreds of feet deep in the earth.
Testing Rivers and Streams for Precious Metals - This is a fast, sure way of locating placer and hard rock deposits of precious metals. The Geochemical Meter can detect both more than a mile downstream from the deposit.
Locating Buried Treasure - All buried treasure eventually creates haloes of metals around it. This halo sometimes extends 100 feet and more depending upon time in the ground. This is true even if the treasure is inside of a cave in a wooden box. Proper use of the Geochemical Meter can be of invaluable use in locating such treasures. The Geochemical Meter does not replace metal detectors, rather use it in conjunction with metal detectors for serious treasure hunting.
Laboratory Testing - The Geochemical Meter will test dissolved geochemicals and metals in water. Many uses can be made of the meter. One suggestion would be to use the meter to tell when the metals have been leached out of an ore when doing cyanide or non-cyanide leaching.
Geochemical Meter
The Geochemical Meter weighs less than one pound. Its approximately 4" x 4.5" x 5" in size and can easily be carried into the field. Most tests should be conducted at home because of the increased accuracy of allowing each test to soak for approximately one hour. 10 or 20 or 100 tests can be set up to soak and then all completed with about I minute per test. Uses 2 standard 9 volt batteries. Several thousand tests can be accomplished on one set of batteries making tests cost less than 1 each. The actual meter readings are in micro mho's. The scales on the meter represent 0-1, 0-100, 0-1000 and 0- 10,000 micro mho's. In some cases a reading as low as 10 can indicate a mineralized vein is nearby. The instruction booklet gives complete details in translating the readings into probability of gold existing nearby and methods of locating same. Action Mining's Geochemical Meter makes geochemical prospecting both fast and accurate when done according to the 30 page instruction booklet which is included.

  How To Use The Meter:
Pulverize your rock to 80 mesh (about the size of table salt) or screen any placer dirt to 50 mesh. Measure out 10 grams. Mix with 40 grams of distilled water and pour into the Geochemical Meter. Push the button on the meter and read the needle. Immediately wash out the meter. Testing streams and rivers is easier. Just pour the water in and push the button. NOTE: To use the Geochemical Meter properly one must first determine the background readings for the area in question. This is accomplished in a very short time through use of the Geochemical Meter.

So tell me one qestion !!!
gold prospectors  have created several sciences
including botany - and it's easy - very easy - plants say it all .

Hi all !!!
answering the question- where can you see it
three hundred years after Albert the Great / creators of botany / a guy
the Pope's confessor had contact with the works of Albert the Great
and lectured at the same University - on his mining field !!!
From the 16th century !!!
I have studied his  mining field carefully and I am surprised by the knowledge of miners from 500 years ago !!

At the first in the world Mining  University - in Banska Stiavnica - botany was taught !!!
