Here’s another chance to play geographical detective! This Multi-angle
Imaging SpectroRadiometer (MISR) image covers an area measuring approximately
297 kilometers x 221 kilometers, and was captured by the instrument’s
vertical-viewing (nadir) camera on April 12, 2001.
A large river flows from the left side of the image, below center, and
traverses the image, angling northeast toward the upper right. It then makes a
hairpin turn and continues to flow in a generally southward direction near the
right-hand side of the image.
Below are eight statements about this river, only some of which are true. Use
any reference materials you like, and mark each statement true or false:
Within the image area, the river flows across an international boundary into
an area where over 100 species of orchids grow.
The river’s name in a particular language means “pacifier” in English.
Sedimentary rocks containing mineral grains that record changes in the
orientation of Earth’s magnetic field have been found north of the river.
At least one expert kayaker has perished attempting to navigate a deep gorge
of the river.
The two highest named peaks within the image area are situated on opposite
sides of the river; each has a maximum elevation of nearly 4000 meters.
The description of a mythical place in a 1930’s British novel is thought by
some explorers to have been inspired by a location on this river.
Scientists believe that 100 million years ago the region through which the
river flows was farther from the equator than it is today.
In the 1920’s, an expedition along the river searched for and successfully
encountered a legendary 30-meter-high waterfall.

Answers will be published on the MISR web site (http://www-misr.jpl.nasa.gov/)
in conjunction with the next weekly image release. The names and home towns of
respondents who answer all questions correctly by the deadline will also be
published in the order responses were received. The first 3 people on this list
who are not affiliated with NASA, JPL, or MISR and who did not win a prize in
the last quiz will be sent a print of the image.
A new “Where on Earth...?” mystery appears as the MISR “image of the week”
approximately once per month. A new image of the week is released every
Wednesday at noon Pacific time on the MISR home page. The image also appears on the Atmospheric Sciences Data Center
home page, though usually with a several-hour
