Atonment. Garden or the Cross?

My next subject of choice, is to cover the Garden or the Cross.
Many LDS member feel the Atonement of Christ took place in the Garden when our Lord sweated great Drops of blood. Not on the Cross as many Believers in the bible alone feel.

I happen to use and like the 1920 edition triple combination bound in leather. In reading the BoM in this edition, I find the word or mention of the Garden in only 4 places.

we find 2 Nephi 2:19 and Alma 42:2 only speaking about Adam and Eve getting thrown out of the garden. And Helaman 7:10 and 9:8,11 speaking about Nephi's garden No mention of the Shedding of Blood for our sins. But we Do read about the Cross or Christ being crucified on the cross for our Sins in the BoM and D and C here in these verses.

Mosiah 3:8-9
Helman 8:14-15 and 14:13-21
3 Nephi 11:14-17 and 20:44 and 27:14 and 28:6-7
Mormon 3:21
Ether 4:1
Moroni 5:1-2 and 10:33
then over in D and C in this long list of verses.
18:11-12 20:23 20:79 21:9 27:2 35:2 45:4,51,52 53:2 76:39,41,69 110:3-5

Now if we look at a few verses in the Old Testament, we find hints of the Cross. We read accounts of the Passover. Their are 71 verses that mention the passover, And when we look at the passover we find the Cross. The blood was put on the door top and sides forming a cross. So when the people would remember the passover they would remember the cross, even though they did not know that was what they were doing.

Another thing we find in the Old Testment in the book of numbers is the placement of the tribes. There were given very specific instructions by God as to how set up camp. some placed in the north, some to the east, some the south and some in the west, with the tabernacle in the center. If you were to hop in a plane and fly over head after this was all set up, you would see the shape of a cross. So every time God looks down at them he see's the Cross, this was what was to come. We do not find this kind of detail about the garden in the Bible or the BoM.

We find a very detailed prophecy of the coming crucifixion of Christ in Psalms 22. We do not read anywhere in the Bible, BoM or any other LDS source this kind of detailed prophecy about the garden.
Below is a list of verses that speak about the Cross.

If any one can show me where the atonment really took place in the Garden please show me. Otherwise I hope you search this out for yourselves, Lest your sins are really not forgiven. How can your sins be really forgiven if the atonment you believe took place in the garden really did not happen their?
