Dynamite is a highly explosive mixture formed by absorbing nitroglycerin into a diatomaceous earth substrate, such as clay.

The Black Rock[]

A cache of extremely old, highly unstable dynamite was discovered in the hold of the Black Rock, very likely intended for use in mining operations when the ship reached America. It appears the stash was first discovered by Danielle Rousseau during her long exile on the Island. The dynamite from this cache was used on a number of different occasions:

Danielle's traps[]

Danielle Rousseau used dynamite from the Black Rock to set at least one trap for the Others.

  • Danielle Rousseau rigged her shelter with dynamite. When Jack and Sayid approached, they inadvertently triggered a tripwire which caused the entire shelter to detonate. ("Numbers")

Blowing open the Hatch[]

Danielle revealed the location of the cache to the survivors, taking Jack, Locke, Hurley, Kate and Leslie Arzt to the old wreck. The survivors carefully extracted six sticks of dynamite to carry in two separate backpacks with the intent to use it to blow open the Hatch.

Battle at the beach camp[]

At Claire's hut[]


  • Richard attempted to commit suicide by lighting a stick of dynamite within the Black Rock. Jack stayed at Richard's side to prove that Jacob brought them both to the island for more of a reason than to die by suicide. Proving Jack's point, the fuse burned out before it could explode. ("Dr. Linus")


The last of the dynamite[]

  • After Ilana's death, Jacob's followers traveled back to the Black Rock to retrieve more dynamite. Hurley, following guidance from the spirit of Michael, snuck onto the ship before the rest of the group arrived and ignited the remaining dynamite, narrowly escaping before the explosion of the Black Rock. ("Everybody Loves Hugo")

The DHARMA Initiative[]

It appears the DHARMA Initiative had their own store of dynamite which was most likely used in ground-clearing for various stations and other facilities on the Island. In 1977 Horace Goodspeed, while intoxicated, was using lit dynamite to destroy trees near the sonar fence. Phil, who was on guard duty at the security office, immediately identified the dynamite upon seeing Horace on the monitor. Later Horace does not recognize the name Black Rock, indicating the dynamite he used came from a different source. ("LaFleur") This further evidenced by Richard resolving to go back to the Barracks where he hoped grenades and dynamite might still be. ("Everybody Loves Hugo")


  • The dynamite transport scene (and Montand's name) are an homage to the movie The Wages of Fear, according to Damon Lindelof in the 5/19/06 podcast. The plot of the extraordinarily tense movie involved transport of dangerous explosives in a desperate situation with few safety precautions. It also featured the idea of separating into two groups that keep their distance from one another, planning for the "worst-case-scenario" of one of them not making it, that the other will reach the destination with adequate explosives to accomplish the mission (much like Jack's idea).
  • Dynamite has played a central role in the season finales of seasons 1-3.
