Trail Marker Fourteen Has Vanished
The class had been following yellow paint blazes through the forest all morning, and Grace was proud that she had counted every single one. Marker thirteen stood beside a large boulder, and marker fourteen, according to the park map, should have been waiting at the next fork, but when the group arrived there, the post was simply gone.
"Now what?" asked Ravi. Two paths curved away between the trees, and neither of them carried any paint.
Their guide, Ms. Alvarez, smiled and folded her arms. "Everybody stay here and use what you already know. I will answer questions, but the decision belongs to you."
Grace unfolded the map on a flat rock. "The trail should bend north at this point, and the creek should be on our right," she said. Ravi raised his compass and turned in a slow circle, discovering that the left path headed north while the right one pointed east. Then they listened, and the faint sound of running water drifted from the trees behind the left path, so the creek was on that side.
"That does not match," said Grace. "We need the creek on our right."
"Unless we are facing the wrong direction," said Ravi. He turned around, and from that position the creek was on the right, while the path to the south led back toward the parking lot that the map showed behind them, so at last they were certain that the trail continued along the left path.
Fifty steps further on, they spotted the missing sign lying in the ferns, and Ms. Alvarez propped it up against a tree.
