Speaking of "Stone Marker", I just finished my review for it. Yeah, there is literally nothing memorable about this episode at all. No wonder it won the "Most Forgettable Episode Ever" title.
THE STONE MARKER OF LEIF ERICSON
MOAT: 4/10
This moat crossing was pretty pathetic. The first player had to paddle across the moat on a log raft. Once they reached the other side, their partner had to cross with the ropes tied to the top and bottom of the pole. The Silver Snakes were very pathetic in this moat. By the time three teams already chimed in for the next round, the Silver Snake player paddling just makes it to the other. -_- You could even see the player struggling to swim across. Really? Even I would've made it across without that much trouble. Eventually, the last team made it across in an very uneventful moat round.
LEGEND: 6/10
500 years before Christopher Columbus, a fierce Viking named Leif Ericson and his longship battled a ferocious storm in the Atlantic Ocean. The waves attacked the boat violently, and the crew paddled where their oars hit the water. Leif's father, Eric the Red, knew that he would be worried about his son and the violent storm kept pushing his crew further away from their destination. By then, Ericson did not know where they were. As lightning lit the sky, Ericson pointed to the West and found land. When the storm subsided, Ericson came upon land filled with trees. He called it "Forest Land", but today it is called America. He carved a Stone Marker so he could return to the land with other Vikings, but no one ever returned...
Not much to say about the legend. It was pretty much a history legend taken right out of your Word History textbook in Middle School. I expected something a little more exciting for a legend about a Viking, but neverthless it was a pretty detailed legend about the discovery of America.
STEPS OF KNOWLEDGE: 6/10
There were a lot of questions asked in this Steps of Knowledge, but that was because all of the teams were chiming in and giving correct answers. The Red Jaguars were the last team to answer a question correctly, but the first team to move onto the temple games. The only other memorable moment was the Purple Parrot player falling down while trying to answer one of the questions.
TEMPLE GAMES: 4/10
The temple games featured the Eric Anderson, who played defender in soccer, and Kelly Anderson, who loved to smile of the Blue Barracudas. Meanwhile, the Red Jaguars featured Keeli, who loved to play on computers, and Chris, who was a second degree green belt in Karate. Note that the Blue Barracudas players both share the same last name and age. It is unknown whether the two players were related though. In general, the temple games were pretty unexciting and there was little competition at all. One player from both teams dominated their individual game.
Temple Game #1 - Raggin the Dragon
During Leif Ericson's time, the bowels of Vikings' ships contained decorations of ferocious beasts like dragons. During this temple game, Keeli and Kelly had to climb the wall and take off pieces of the dragon decoration. Once they take off all of the pieces of the dragon, they had to climb back down to the bottom. Kelly was the more dominant player in this temple game and had most of the dragon disassembled before Keeli start working on hers. She won the first half-pendant for the Blue Barracudas.
Temple Game #2 - Build a Stone Home
Chris and Eric had to build a house of their own by digging through a quarry for rocks and climbing to the top of the quarry to place their rocks. The player that had the most rocks at the end of 60 seconds would be the winner. Chris was the more dominant player in this temple game and won with a score of 5-2.
Temple Game #3 - Traveling Vikings
The Vikings use to travel all the time between Finland and Greenland. In this temple game, the players had to help the Vikings travel from Finland to Greenland. One player had to grab the Viking doll from their partner's head while the other player had to grab the Viking doll and put it into their team's bucket. The player with the most dolls would be the winner. Unlike the last two games, this temple game was very close and the Blue Barracudas were actually leading at one time. But the Red Jaguars pulled ahead and got all 5 dolls into their bin to gain the rights to Olmec's temple.
TEMPLE RUN: 5/10
Season One had some inconsistent layers where the temple run featured either an easy or brutal layout. The Red Jaguars in this episode featured a brutal layout. In fact, their temple layout was exactly a cookie cutter of the one used in "The Paintbrush of Leonardo Da Vinci". Keeli started in the Room of the Three Gargoyles, but after not trying all three tongues, she was forced down into the Wheel Room. After completing the Wheel Room and Room of Harmonic Convergence, she meets a rare and one-time only temple guard in the Bamboo Forest that apparently scared her a lot. The Bamboo Forest was a deadend for Keeli though and she was forced to retreat back to the Harmonic Convergence and forced up the central shaft. In the Observatory, she encounters her second temple guard and lets out a earth shattering scream!

Chris follows Keeli's steps, but he doesn't have enough time to make anymore progress.
Not much to say about this temple run except the producers expected too much from these kids. It's a shame that they had to reuse the exact same temple layout from the production day before it. It didn't help though that Keeli never tried all 3 tongues in the Gargoyle Room. There was literally nothing that happened in this temple run though. The Red Jaguars weren't a bad team though, they got caught up in a brutal and time-consuming dead end.
FINAL VERDICT: 5.0/10
"Stone Marker" is one of the most forgettable Legends episodes on the show. In fact, it won the title "Most Forgettable Legends Episode Ever" in a competition that was held in the Temple Games forum. It was just an average episode in every sense and most likely you won't even know this episode exists because there is
nothing to talk about. Every round was just average and there is not even a noteworthy detail to point out. You should definitely watch this episode for the sake of completion. Other than that, this was a boring and uneventful. You wouldn't miss anything by not watching it at all.
On another note though, there has been a recent interview with Keeli of the Red Jaguars on the internet. Some highlights of her interview include how she had to start her temple run over a few times and how she thought her partner Chris was stupid. Definitely worth a read if you have watched this episode.
