Post-publication careers: follow-up expeditions reveal avalanches at Dyatlov Pass
No full textHaving shed new light on an old mystery-how nine Russian mountaineers perished in the Urals in 1959-Alexander Puzrin and Johan Gaume got hooked. Three expeditions later it is clear that avalanches are not exceptional at Dyatlov Pass.SLA

<p>contain the data for spacing and depth of the crevasses in the different simulations. Each simulation folder is named after the ice thickness H and cohesion c. For example, H300c2 means an ice thickness of 300m and a cohesion of 2MPa.</p>
<p>The simulation files contain data measured every 10 frames. Empty files imply two possibilities:<br>-the crevasse(s) are away from the window measurement (the window is approximately 1500m wide around the obstacle).<br>-No crevasses are observed or at least no distinguishable enough.</p>

<p>The full simulation results cannot be transfered as a supplementary material as it is too large (20Go for each simulation). However we provide two full result files: <strong>H300_c0_4.abc</strong> and <strong>H100_c2.abc. </strong>We provide an example of the init.lua file used to launch a simulation with given parameters and configurations. The configurations used in the simulations are all provided in the geometry.zip file.</p>

Report of Governor Johan Rising, 1655, on New Sweden
No full textGovernor Johan Rising reports to the Swedish government and royalty on the status of New Sweden (present-day New Jersey). He also reports on other Swedish colonies in the area. He asks that single women and skilled tradesmen be sent to the colonies. Rising also reports that attacks from neighboring Indian tribes are increasing. He has found some protection by forming an alliance with English settlers, but the cost is high, and his colony owes the English money and supplies. Rising asks that Sweden send them money so that they can pay off their debts, build ships that would establish a trading dominance with the West Indies, and cultivate land and crops to gain more profit. Reports from New World governors were sent back to their native countries via ships. Rising sent this report in June of 1655, but Sweden did not recieve the report until November of 1655.

Report of Governor Johan Printz, 1647, on New Sweden
No full textGovern Johan Printz, the governor of New Sweden (later to become New Jersey), reports on the status of the colony and the settlers. Many freemen have arrived to settle in New Sweden, but the criminals and military men who were conscripted to the colony want to return to Sweden. Of the freemen, very few are skilled, so Governor Printz asks that blacksmiths, tanners, tailors, carpenters, and butchers be sent to the colony. Additionally, he asks for single women. Printz also reports on two new Swedish colonies that have been established along the Delaware River. However, Dutch settlers have become very aggressive by re-purchasing land from the Indians that the Swedish had already bought. They are also interrupting trade between the Swedes and the Indians, as well as instigating the Indians to attack the Swedes. Printz directed the construction of some storage houses along common trade routes to win back trade from the Indians. However, fighting has erupted between different Native tribes as each tries to establish dominance in trading with the colonies.

Relation of the surrender of New Sweden, by Governor Johan Clason Rising, 1655
No full textGovernor Johan Rising of New Sweden reports to Sweden on the August 1655 Dutch attack on New Sweden's Fort Christina. The Dutch traveled from New Amsterdam (present-day New York) and easily captured a New Sweden outpost. Rising sent men to the outpost to fend of the Dutch, but the Dutch defeated them and took them as prisoners, leaving Fort Christina without fighting men and supplies. The Dutch then put the Fort under seige. A few days later, Rising surrendered the Fort. He and the Swedish colonists were ordered to either return to Sweden, or to remain in the New World in service to the Dutch.
