In the heart of the Gizeh desert, Indiana Jones stumbles upon a Nazi-guarded meteorological station hiding a cryptic puzzle known as the Cloud Atlas Mystery. To unlock a chest containing vital treasures, players must decode a secret combination by cross-referencing cloud formations recorded on specific dates-a challenge that blends keen observation with clever deduction. Crack the code 0609, and uncover not only cash but a crucial map revealing hidden medicine collectibles, turning this atmospheric enigma into one of the game’s most rewarding adventures in Indiana Jones and the Great Circle.
How to start the ’Cloud Atlas’ mystery
To start the “Cloud Atlas” mystery in Indiana Jones and the Great Circle, head to the Meteorological Station located near the center of the Gizeh map, just west of the Great Sphinx. The station consists of two Quonset-like huts guarded by Nazi soldiers. Carefully sneak past or eliminate the guards to access the tents. Inside the left tent, find two crucial documents-the Cloud Status Logbook and the Cloud Atlas Page-which contain the clues needed to decode the combination for the locked chest in the right tent. By cross-referencing cloud types recorded on specific dates in the logbook with the numbered cloud classifications on the atlas page, you can determine the chest’s code and unlock the mystery.

To start the “Cloud Altas” mystery, you just have to reach the Nazi Meteorological Station in Gizeh. You’ll find it just west of the Great Sphinx and south of the Nazi Recreation Area near the center of the map.
You’re looking for a pair of Quonset huts (well, proto-Quonset huts since these are a few years too early?) guarded by a trio of Nazis.
’Cloud Atlas’ clues and hints
The “Cloud Atlas” mystery in Indiana Jones and the Great Circle is a side quest located at the Meteorological Station west of the Great Sphinx in Gizeh. To solve it, players must decipher a combination lock on a chest by using two key documents found inside a tent at the station: the Cloud Atlas Page and the Cloud Status Logbook. The Cloud Atlas Page lists cloud types with corresponding numbers, while the Logbook records cloud observations at specific times. By matching the cloud names from the Logbook to their numbers on the Atlas Page and following a sequence of dates and times, players can derive the four-digit code (0609) needed to unlock the chest. The puzzle involves careful observation and pattern recognition of cloud classifications such as Cirrus, Stratus, and Cumulonimbus, making it a clever meteorological cipher that rewards players with valuable loot for Indy’s journey.

The chest you’ll be opening is in the room on the right. Over on the left, you’ll find a room with a bunch of radio equipment and two notes – a Cloud Status Logbook and a Cloud Atlas Page.
The logbook lists a series of times and types of clouds. The atlas page has the types of clouds associated with numbers.
’Cloud Atlas’ chest code solution
The solution to the “Cloud Atlas” chest code puzzle in Indiana Jones and the Great Circle involves deciphering a code from two key documents found at the Gizeh Meteorological Station: the Cloud Atlas Page and the Cloud Status Logbook. The Cloud Atlas Page lists various cloud types with corresponding numbers, and four specific dates are noted at the bottom. By cross-referencing these dates with the cloud observations recorded in the Cloud Status Logbook, players identify the clouds as Cirrus, Stratus, Cirrus, and Cumulonimbus. Matching these cloud types to their numbers on the Cloud Atlas Page yields the chest code 0609. Entering this code unlocks the chest, granting players cash, adventure points, and the Gizeh Medicine Exploration Map, which highlights all medicine bottle locations in Gizeh for further exploration and upgrades.

To find the code, you have to take the handwritten times at the bottom of the Cloud Atlas Page, and reference them against the Cloud Status Logbook to find what types of clouds you’re looking for. The times are 13, 9, 16, and 14 (ignoring the 10 after because it doesn’t matter).

On the Cloud Status Logbook page, these times have Cirrus, Stratus, Cirrus, and Cumulonimbus observed. Back on the Cloud Atlas Page, these become the code for the chest in the other room – 0609.
What secrets does the Cloud Atlas puzzle reveal in Indiana Jones
The Cloud Atlas puzzle in Indiana Jones and the Great Circle reveals a locked chest containing cash and the Gizeh Medicine exploration book, which helps locate medicine collectibles in the region. To solve it, players must decode a combination lock by matching cloud types observed on specific dates with their corresponding numerical codes from a Cloud Atlas Page. The final code is 0609, derived from the clouds Cirrus (0), Stratus (6), Cirrus (0), and Cumulonimbus (9) recorded on the dates October 13, 9, 16, and 14 respectively. Unlocking the chest not only yields valuable loot but also grants 225 Adventure Points and a crucial map aid for the Gizeh area.
What hidden message or secret does the Cloud Atlas puzzle conceal in Indiana Jones
The Cloud Atlas puzzle in Indiana Jones and the Great Circle conceals a secret code to unlock a chest at the Nazi Meteorological Station in Gizeh. This code is derived by decoding cloud types recorded on specific dates using two notes found at the station: the Cloud Atlas Page, which assigns numbers to different cloud types, and the Cloud Status Logbook, which logs the clouds observed on those dates. The hidden message is a numerical combination-0609-corresponding to the clouds Cirrus (0), Stratus (6), Cirrus (0), and Cumulonimbus (9). Unlocking the chest reveals valuable loot including cash and the Gizeh Medicine exploration book, which aids in locating medicine collectibles in the region. Thus, the puzzle’s secret is both a cipher and a key to further exploration and rewards in the game.
