I had been camped with a group of 4 people including myself at location 49â°35'37.8"n 115â°18'52.2"w. we were kayaking the bull river together. after our last run on the 19th the rest of the group left by about 4:30 pm and i remained. i had finished dinner and was sitting facing north at approximately 6:20 pm. i noticed a black object appear over the mountain range on my left (west) traveling in a slight arced path to the east. the object was in view until it past the mountain range to the east of my location. i had visibility to the object for roughly 12 seconds. if i had to estimate its velocity it would be about ~300kmh. the object was a black sphere. my best estimate for size would be a diameter of the length of a vw camper van. it was all black except it had a shimmer like black silk reflecting light. i did not hear it make any noise but was camped next to the bull river. the fast water was loud so it could have drowned out any noise the sphere may have potentially made. there were no wings, no evidence of jet propulsion, no odour detected. the vehicle was clearly observable but not enough time was available to take pictures. i did find a video on youtube that is identical to what i saw https://www.Youtube.Com/watch?V=crwrfw-qvj8. no events occur after and no sitings of the sphere for the next two days in the area. nothing else relevant to report
