Hello MArk

Well done on the lighting. No hard shadow to cut accross subjects. Looks like you found the perfect spot. Nice. Not as easy as it looks in the Arizona high country. Keep them coming

Default To ikeharel: 1.8 m/day

Hi Ike,
Those marks cannot be millions of years old. Margerie flows at 1.8 m/day and it is 34 km long. If those streaks had been formed right at the origin, it would have taken them 34,000/1.8 = 1888.88 days = ~52 years to reach the terminus. So they can't be older than 52 years.
