The homeless man wore a Cap’n Crunch cereal box on his head, and told Caden there is not telling how deep the subway goes. There, he discovers candy treasure, and recalls a memory of a homeless man during a visit to New York. So much change causes Caden to reel mentally, during which time he descends to the bottom of the Marianas Trench. Callie, with whom Caden has grown close, is released from the hospital. Carlyle is unfairly blamed for the incident, and fired. Tragedy strikes, however, when Hal attempts suicide by slitting his wrists.
In Caden’s mental reality, the better Caden gets in real life, the closer he and the Captain draw to the Marianas Trench. Piece by piece, Caden begins to emerge from his illness. There is the navigator, Hal, who obsessively seeks to find patterns in maps and who serves as Caden’s roommate at the hospital there is the beautiful but distant Callie who appears on ship as the wooden maiden and there is Carlyle, the group therapist who appears on the ship as the swabby.Īs the weeks pass, Poirot and Carlyle work to get to the heart of whatever illness Caden has contracted through medication and through therapy. All of the crewmembers onboard that Caden encounters are mirror images of the patients he meets at Seaview. Poirot who comes to treat Caden at Seaview. The Captain of the expedition is accompanied by a security parrot, a mental mirror for Dr. The Captain tells Caden that there is no telling how deep the Trench, or Caden’s illness, actually may go. Caden’s parents commit him to Seaview Memorial Hospital for treatment while Caden continues to spiral. Caden feels outside himself, existing both in his mentally-constructed world, reality, and sometimes a blend of both. The Captain says there is no telling how deep it goes.Ĭaden agrees to go on this expedition, which signals his descent into illness. The Captain forms the backbone of the illness for Caden, in which a pirate-like world is created wherein the Captain seeks to explore Challenger Deep, the deepest part of the Marianas Trench, the deepest area in the world. Over the past several months, Caden has slowly lost his grip on reality, unable to focus on anything, constantly needing to walk, believing a kid at school wants to kill him, and being visited by a pirate Captain. Caden understands that there are two worlds – one that is real, and one that is real in his mind. In a wider perspective, the interrelations shown here between trench deepening, ridge shallowing, slab steepening, and forearc narrowing may shed light on other subduction zones located near edges of rapidly steepening slabs.“Challenger Deep” is a young adult novel by Neal Shusterman that follows 15-year-old Caden Bosch as he descends into mental illness, and recovers. In addition, a tear in the slab beneath this region helps it to sink rapidly through the mantle, and this combination of circumstances allows the slab to steepen and form the deepest trench on the Earth. In contrast, along the south Mariana Trench the subducted length of the lithosphere is much shorter, but its attachment to the upper plate is only along a relatively narrow, 50-km-wide, surface. Beneath the central Marianas the subducted slab is attached to the upper plate along a 150-km-wide surface that holds the shallow portion of the subducted plate nearly horizontal, in spite of its great load and, thus, counters trench deepening. However, why is it located in the southernmost Mariana Trench and not at its central part, where the rate of subduction is higher, where the lithosphere is the oldest (and densest) on the Earth, and where the subducted lithosphere pulling down is the longest in the Earth (∼1000 km or more according to seismic tomography)? We suggest that although subduction rate and slab age generally control trench depth, the width of the plate-coupling zone is more important. Its location within a subduction trench, where one plate bends and descends below another, is not surprising. The Challenger Deep in the southernmost Mariana Trench (western Pacific Ocean) is the deepest point on the Earth's surface (10,920 m below sea level).
