The following demonstrates a reliance on written tradition, no doubt there is a spattering of oral tradition sprinkled about the gospel storyline here and there, but the gospel of Mark shows the use of scriptures dominate his allegorical fiction. I can provide the same for almost if not every scene described in the gospel.

"The Cursing of the Fig Tree and the Disruption at the Temple:
The cursing of the fig tree and the clearing of the temple in the Gospel of Mark are based on a passage from the Hebrew scriptures. This is a significant scene and use of literary allusion because the cursing of the fig tree seems very hard to explain or understand if one does not understand that the scene is actually a reference to another text. This is also significant because it undermines the historical credibility of the temple scenario.
Mark 11:
12 The next day as they were leaving Bethany, Jesus was hungry. 13 Seeing in the distance a fig tree in leaf, he went to find out if it had any fruit. When he reached it, he found nothing but leaves, because it was not the season for figs. 14 Then he said to the tree, "May no one ever eat fruit from you again." And his disciples heard him say it.15 On reaching Jerusalem, Jesus entered the temple area and began driving out those who were buying and selling there. He overturned the tables of the money changers and the benches of those selling doves, 16 and would not allow anyone to carry merchandise through the temple courts. 17 And as he taught them, he said, "Is it not written:
"'My house will be called a house of prayer for all nations'? But you have made it 'a den of robbers.'"18 The chief priests and the teachers of the law heard this and began looking for a way to kill him, for they feared him, because the whole crowd was amazed at his teaching.
19 When evening came, they went out of the city.20 In the morning, as they went along, they saw the fig tree withered from the roots. 21 Peter remembered and said to Jesus, "Rabbi, look! The fig tree you cursed has withered!"
This entire scene is based on Hosea 9, and refers to the destruction of Israel.
NIV
Hosea 9:
1 Do not rejoice, O Israel; do not be jubilant like the other nations. For you have been unfaithful to your God; ...
7 The days of punishment are coming, the days of reckoning are at hand. Let Israel know this. Because your sins are so many and your hostility so great, the prophet is considered a fool, the inspired man a maniac.
8 The prophet, along with my God, is the watchman over Ephraim, yet snares await him on all his paths, and hostility in the house of his God.
9 They have sunk deep into corruption, as in the days of Gibeah. God will remember their wickedness and punish them for their sins.
10 'When I found Israel, it was like finding grapes in the desert; when I saw your fathers, it was like seeing the early fruit on the fig tree. But when they came to Baal Peor, they consecrated themselves to that shameful idol and became as vile as the thing they loved.
11 Ephraim's glory will fly away like a bird—no birth, no pregnancy, no conception.
12 Even if they rear children, I will bereave them of every one. Woe to them when I turn away from them!
13 I have seen Ephraim, like Tyre, planted in a pleasant place. But Ephraim will bring out their children to the slayer."
14 Give them, O LORD—what will you give them? Give them wombs that miscarry and breasts that are dry.
15 "Because of all their wickedness in Gilgal, I hated them there. Because of their sinful deeds, I will drive them out of my house. I will no longer love them; all their leaders are rebellious.
16 Ephraim is blighted, their root is withered, they yield no fruit. Even if they bear children, I will slay their cherished offspring.'
17 My God will reject them because they have not obeyed him;
We can clearly see here that the author of Mark uses Hosea 9 for his motif, because in Mark 11 the fig tree is in leaf but not in season, meaning that it was early in the growing season. Then Jesus goes to the temple to drive the people "out of his house". After that they return to the fig tree where they see that it was withered "from the root." This makes the parallel between Mark and Hosea 9 very clear, and shows that Hosea 9 was the inspiration for all of these scenes. The author of Mark was also clearly making a reference to the meaning in the text of Hosea 9. Hosea 9 is talking about the destruction of Israel in no uncertain terms.
This is quite significant because it strongly undercuts the temple disruption scene as a historical event, despite the fact that the temple scene is contained in all three of the other Gospels. The temple scenes in all three of the other Gospels are based on this scene in the Gospel of Mark, which is really a literary allusion."
The Gospel of Mark as Reaction and Allegory

Now perhaps you can provide evidence for an oral tradition that "spawned it."
