Ascension Chapter 4: Thursday, 24th January 1991
⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
Harold Tunmore writes to Harriet from Base Camp, 15,000 feet up the mysterious new mountain in the South Pacific. After a harrowing helicopter ride that floods him with a sense of yūgen—the overwhelming awareness of the universe’s immensity—he meets geologist Thomas Fung, who is starstruck by Harold’s reputation. The expedition leader, Major Bautista (called “the Warden”), introduces a strict acclimatisation schedule. Harold secretly explores the camp and encounters a worker with a bloody nose whose face seems to age and then de-age before his eyes. At the evening briefing, Colonel Palmer reveals that only two of the ten-person first expedition returned: John McAllister and Dr. Naoko Tanaka. The mountaineer Sir Roger Bettan insists on a rapid ascent to beat the monsoon window. Later, chemist Jet Towles visits Harold’s tent with smuggled rum; they discuss science, religion, and Jet’s preliminary chemical findings (magnesium degrades in five hours instead of weeks). The Warden then takes Harold to see Naoko, who is locked in a cabin and has covered every wall with chalk marks to “keep time.” When Harold steps into the light, she screams until he leaves.
Key Events
- Harold arrives at Base Camp by helicopter, experiencing a profound yūgen moment.
- He meets Thomas Fung, a geologist, and learns that the mountain is estimated at 38,000–42,000 feet.
- Harold attempts to question workers but is rebuffed; one worker’s face briefly appears younger.
- Colonel Palmer and Major Bautista conduct a formal briefing, introducing the science team: chemist Jet Towles, geologist Thomas Fung, physicist Harold Tunmore, and an anthropologist and biologist (Polya Volikova and Dr. Amai) waiting at Camp One.
- Sir Roger Bettan, an Australian Special Forces mountaineer, outlines an aggressive ascent schedule, overruling Jet’s concern about altitude sickness.
- Palmer reveals that the first expedition ended with only two survivors—McAllister and Tanaka—and that the rest are presumed dead on the upper mountain.
- Jet shares his discovery that magnesium in ice samples degrades in five hours, far faster than expected.
- The Warden takes Harold to Naoko’s locked cabin; she has covered the room in tally marks and screams when she sees Harold.
Character Development
Harold Tunmore continues to wrestle with his past (the “tungsten box” of memories) while trying to stay scientifically detached. His decision to sneak around the camp shows both curiosity and growing suspicion. The reunion with Naoko cracks his composure completely, revealing deep unresolved guilt and sorrow.
Naoko Tanaka appears only at the chapter’s end but makes a lasting impression. She is shown as traumatised, paranoid about time, and isolated from the rest of the team. Her scream suggests either a terrible recognition of Harold or a fear triggered by his presence—a sign that her experience on the mountain has left her psychologically fractured.
Jet Towles introduces a youthful, irreverent energy. He is enthusiastic about the mystery, openly critical of religion, and eager to bond with Harold. His chemical finding hints that the mountain operates under altered physical rules.
Thomas Fung remains guarded but polite. His deference to Harold and his observation about Bettan’s schedule show him to be both competent and cautious.
The Warden (Major Bautista) continues to evoke mistrust. He speaks of Naoko with clinical detachment yet shows compassion by arranging the night-time visit. His role as Palmer’s subordinate is now explicit, but his earlier independence complicates the power dynamic.
Themes, Symbols, or Motifs
- Yūgen: Harold’s helicopter ascent triggers this Japanese concept of profound insignificance and harmony. It becomes a lens for understanding how the mountain dwarfs human ambition.
- Time and Obsession: Naoko’s chalk marks obsessively track days. The motif reappears in Jet’s accelerated chemical degradation and the compressed ascent schedule. Time on the mountain seems untrustworthy.
- Secrecy and Surveillance: Guards, padlocked cabins, and unanswerable questions (Where is Naoko? What happened to the first expedition?) build an atmosphere of clandestine control.
- The Sublime in Nature: The mountain forces a physical and psychological reorientation; Harold’s previous scientific certainty is shaken by its sheer scale and inexplicable existence.
Why This Chapter Matters
Chapter 4 moves the story from the world’s confusion to the mountain’s intimate tension. It establishes the core expedition team, hints at the mountain’s anomalous properties (fast chemical decay), and provides the first direct look at the trauma that survivors carry. Naoko’s scream becomes a visceral cliffhanger that sharpens the central mystery: what happened on that first climb, and why does Harold’s presence trigger such a reaction? The chapter also deepens the character of Harold by exposing his emotional vulnerability beneath the scientific exterior.
Study Questions and Answers
1. Why does Naoko scream when she sees Harold?
The text does not give a definitive explanation. It may be that Harold’s resemblance to someone from her traumatic experience triggers her, or that his arrival represents a threat or a painful reminder. The Warden describes her as paranoid and obsessive, so any familiar face could destabilise her fragile state.
2. What does Jet’s magnesium experiment suggest about the mountain?
The magnesium sample degraded in five hours instead of the expected weeks, implying that the mountain’s atmosphere or rock accelerates chemical processes. This anomaly supports the idea that the mountain operates under different physical laws, a key part of the novel’s mystery.
3. How does the briefing scene create dramatic tension?
Colonel Palmer withholds key details (the nature of the “anomalies,” what the first expedition found), while Bettan’s aggressive demeanour and urgent timeline pressure the team. The revelation that only two of ten survived, and that one of them is now screaming in a locked cabin, hangs over every decision.
