Ms. Doogan moved up the trail about ten feet. It was starting to get steep and the snow on either side of the trail to get higher. At the same time they could hear the sound of running water. “The glacier was here in 1898. What happened in 1898?”

Betty opened her mouth but Vanessa beat her to it. “The Klondike gold rush.”

“Very good, Vanessa,” Ms. Doogan said. “Have you been reading ahead in your history book?”

Vanessa gave her solemn nod.

“And you’re remembering what you read. Good job.”

Betty was much too mindful of the might and right of authority to do anything so lese-majeste as to pout, but Moira Lindbeck was close to dancing in the street. Ms. Doogan fixed her with a quelling eye, and led the way to the next signpost. “In 1914, the glacier was-”

“World War One!” shouted Laurie Manning, capering up and down in excitement. Laurie had yet to master middle-school cool. “World War One! World War One!”

There was a soldier or soldiers in Laurie’s future, Ms. Doogan thought with an inner sigh, but she smiled and said, “Yes, Laurie, World War One. Eric Kizzia, if you pinch Mary Lindbeck one more time, I’m going to pinch you myself, in the same place and just as hard. Knock it off.”

Eric tucked prudent hands into the pockets of his corduroy jacket and did his best to look as pure as the driven snow. His grin was impudent and dimpled and it was hard not to grin back. He’d had a crush on Mary Lindbeck since the second grade, only temporarily sidetracked by luscious upperclassman Tracy Drussell last year. Eric’s plan had been for Tracy to flunk until Eric made it into her class, but Tracy ’s family had moved to Anchorage instead, and in the interim Mary had grown breasts, which had effectively cut short Eric’s mourning for Tracy. It also made it difficult to keep his hands to himself. If he’d tried to hold her hand, Mary would have shoved him into the ditch with the wild rice. Ignoring her was not an option. A pinch had seemed a safe compromise.
