Dare to Ski
Skiers dare each other to challenge the runs at Big Roundtop in this downhill Logic Puzzle.
January 13, 2003
From the introduction, all five boys skied the 1st run, then one boy dropped out before the 2nd, 3rd, etc., until only one skied the 5th run. Neither the Two Towers (clue 2), Slingshot (3), nor Spider's Web (4) run was the 1st one, which all five skied; so either the Grizzly Bear or the Lonesome Pine was. If the Grizzly Bear had been the 1st run, then by clue 1, the Lonesome Pine run would have been the 2nd or the 3rd run the boys tested. If the Lonesome Pine had been the 2nd run, then Brent would have quit right after skiing it and before the 3rd run, and Mayer would have dropped out of the dare just before the 4th test. Then Johnson in clue 2 would have quit before either the 3rd or the 5th run. If Johnson had quit before the 3rd run, he would be Brent, the 3rd run would have been the Two Towers, and Evan would have quit immediately before the Lonesome Pine run. By clue 4, Wilcox would have dropped out right before the 5th-run Spider's Web; and, by clue 3, Chris would have quit before the 4th-run Slingshot. Either Alex or Dan would be the one who finished all five runs; since neither is Shaffer (5), Shaffer would be Evan--a contradiction, since Evan would have quit just before the Lonesome Pine challenge and Shaffer finished that run (5). So, given that the Grizzly Bear and Lonesome Pine are the 1st and 2nd runs, Johnson couldn't have quit before the 3rd run. If Johnson had quit before the 5th run, it would be the Two Towers and Evan would be Mayer (2). But there is no way for clue 3 to work. So, there is no way for the Lonesome Pine to be the 2nd run if the Grizzly Bear had been the 1st one tried. If the Grizzly Bear had been the 1st one tried and the Lonesome Pine had been the 3rd, by clue 1, Brent would have dropped out of the dare just before the 4th run, and Mayer would have quit immediately ahead of the 5th run (1). By clue 2, then, since Johnson was second or later to quit the challenge, Johnson would be Brent, the Two Towers would have been the 4th run, and Evan would have quit just before the Lonesome Pine test. By clue 4, Wilcox would have quit right before the 2nd-run Spider's Web; and by clue 3, Chris Mayer would have quit just before the Slingshot challenge. Either Alex or Dan would be the one who finished all five runs; since neither is Shaffer (5), Shaffer would be Evan--again a contradiction, since Evan quit just before the Lonesome Pine trial and Shaffer made that run (5). Therefore, there is no way for the Grizzly Bear to be the 1st run, so the Lonesome Pine run is. By clue 1, then, Brent was first to drop out, quitting right before the 2nd run; and Mayer quit just before the 3rd test. By clue 2, Johnson quit right before either the 4th or the 5th run. If he had dropped out right before the 5th trial, which would be the Two Towers, Evan would have quit just before the 4th run. By clue 3, Chris would be Mayer and would have retired right before the Slingshot. Also by clue 3, the Grizzly Bear would have been the 2nd run. Then Wilcox would be Evan (4)--no (6). So, Johnson dropped out before the 4th run--the Two Towers, with Evan being Mayer. Since Chris quit right before the Slingshot (3), it must be the 5th run. Wilcox, who quit just before the Spider's Web (4), is Brent. By elimination Evan Mayer didn't like the look of the Grizzly Bear. By clue 5, Chris is Shaffer; and Loudon won the dare by making all five ski runs. Loudon is Dan and Alex Johnson (2). In sum, the Ski Dare reults were

  • No Dropouts - Lonesome Pine
  • Brent Wilcox - Spider's Web
  • Evan Mayer - Grizzly Bear
  • Alex Johnson - Two Towers
  • Chris Shaffer - Slingshot
  • Dan Loudon, winner
