The following exert is an eye witness statement. Please read into it what you will. This has been reported to mufon who I am sure are investigating:
i was hiking in the mount lassen national forest, near the southwest entrance of mount lassen national park. i photographed some trees with interesting moss patterns with my nikon d810 camera. i did not notice the objects until i was editing my photos the next day. at the time, the forest area was very quiet; there were no aircraft in the area and no extraneous noise, other than birds and light wind noise through the pine trees.
i have no idea what these objects are. as i said above, i did not notice them at the time of the photographs. i took 6 photos of the trees within one minute. the objects appear in two frames which, given that the d810 can take photos at 4-5 frames a second, means the objects were in the two frames for only fractions of a second. the size of the objects are hard to determine. they appear to be distant and traveling fast.
my after the fact reactions are curiosity, of course, and i would like to know what these strange objects are. i have contacted nasa, the air force, local tv, and the park service without any resolution as to what the objects are and if anyone else saw them.
