From the Archbold´s notes:


American Richard Archbold, scouting his third expedition to New Guinea, was the first outsider to lay eyes on the magnificent Grand Valley of the Baliem. As he peered out of the window of his sea plane on June 23, 1938 the terrace green fields of the valley appeared from among the rocky peaks like a mirage. The 14-month highland expedition was Archbold's third in New Guinea (the other two were in eastern New Guinea), all under the auspices of the American Museum of Natural History. Archbold is a mammalogist and explorer as well as millionaire. At first, the bureaucrats in Batavia (now Jakarta) were reluctant to produce the needed permits, but then the Dutch colonial government decided to co-sponsor the trip. Soon, dozen of men and tons of material were heading for Hollandia (now Jayapura), the population of which at the time were barely 200: government personnel, their servant Indonesian artisan and Chinese traders. The area chosen for exploration was the northern face of the snow Mountain-range-the largest remaining blank on the map of New Guinea at the time. Previous expedition had explored the southern slope of this impressive range, returning with important biological collections. And though 1921-1922 Kremer expedition had succeeded in reaching the North Slope of the Snow Mountains, Kremer had to abandon his precious collections to the jungle on the exhausting trek back to the coast.

The Guba
The key to the Archbold expedition's success was a huge Catalina flying boat called the Guba. The craft was a consolidate PBY 2, the standard US long-range patrol bomber, that had been specially modified by Howard Hughes for Salmon fishing expeditions to Alaska and then subsequently sold. Expert considered it the most air- and seaworthy aircraft in existence at the time. Lift was provided by a 31,7 meter wing, which supported a 20,4 meter fuselage. The plane was powered by two 1,000 HP Pratt and Whitney Twin Wasp engines fed from a 1,750 gallon fuel cell and holding 110 gallons of oil in the crankcases. The Guba could lift three tons at sea level and cruise for a distance of 800 kilometers, but when taking off 3,225-meter-high Lake Habbema, the payload had to be restricted to just one ton of cargo and a standard crew of four men.

It was during one of the exploratory flights of the Guba that Archold first sighted the Baliem Valley. Immediately, he realized the importance of his discovery. He was looking at the largest highland valley in New Guinea, as well as the most densely populated. Of course, he did not suspect that the Dani inhabitants were also the highland's most feared warriors. Archold saw the Dani's watchtowers, but did not guess that their purpose was to keep an eye out for enemy ambush parties.

Getting Underway
Archold and the Dutch military members of the expedition decided to set up two campsin the interior of Irian : a high one on Lake Habbemaat 3,225 meters and a low one in the Meervlakte (the "Lakes Plains" region north of the mountains), 50 meters above sea level. The area to be studied was bounded by mount Wilhelmina (now Gunung Trikora) on the south and the Idenburg River (now Taritatu) on the north. The military arm of the expedition, under the command of Captain Teerink and Lieutenant Van Areken, consisted of 56 officers and men. The porters included 73 Dayaks (the mountainous terrain of their homeland Borneo equipped them well for Irian's rugged landscape) and 30 convicts.

The Dutch authorities did not want to lose American lives, and the military men ordered that precautions be taken. Foremost in their minds was an emergency retreat route, should the Guba for some reason be unable to pick up the party at Lake Habbema. So men, equipment and supplies were flown up to the Idenburg River, which offered relatively easy river access to Irian's north coast. Aerial reconnaissance was crucial in determining the best route (about 100 kilometers in a straight line) between Lake Habbema and the Idenburg camp. The military patrols were to leave from each of the two staging areas and meet up in the Baliem Valley. Shortly after Lt. Van Areken"s patrol cut upward from the Idenburg River, the group experienced a pleasant surprise: a large, heavily populated valley and, best of all, a lake, immediately dubbed "Lake Archbold". Located about one kilometer from the Habifluri River (which flows into the the Vande meters, at an altitude of 700 meters. Once the Dayak chopped down some trees for the approach, the Guba could land on the lake to bring in supplies. From Lake Archbold, the going really got tough-steep climbing through forest, and no trails.

Once the party began to approach the Baliem Valley, the local highlanders becomes numerous and friendly. To friendly, in fact. In several villages, Lt. Van Areken was welcomed with food, but the tribesmen did not want to leave the party. Only the "utmost determination" kept the group moving, according to the expedition journal. One day after a friendly reception, the party found their path blocked by a barricade of warriors with spears. The journal laconically states "Here occurred the one incident where more than a show of force was necessary".
