Narrative:

Den tower gave us a low altitude warning while making a visibility approach to runway 26R. Altitude was low because letdown was being made to an area off the airport that had been misidented as the runway. Problem arose by feeling pressure to identify the runway too early in poor visibility (4 mi in haze). Other contributing factors were an early get up on the east coast for west coast pilot, a long 6 1/2 hour flight (delayed 2 hours on ground after leaving gate). I know better than to start letting down unless there is no question about runway identify, but I guess fatigue set in and I let my guard down.

Title: ACR MLG RECEIVES A MSAW WARNING WHILE ON A VISUAL APCH TO RWY 26R AT DEN.

Narrative: DEN TWR GAVE US A LOW ALT WARNING WHILE MAKING A VIS APCH TO RWY 26R. ALT WAS LOW BECAUSE LETDOWN WAS BEING MADE TO AN AREA OFF THE ARPT THAT HAD BEEN MISIDENTED AS THE RWY. PROB AROSE BY FEELING PRESSURE TO IDENT THE RWY TOO EARLY IN POOR VISIBILITY (4 MI IN HAZE). OTHER CONTRIBUTING FACTORS WERE AN EARLY GET UP ON THE E COAST FOR W COAST PLT, A LONG 6 1/2 HR FLT (DELAYED 2 HRS ON GND AFTER LEAVING GATE). I KNOW BETTER THAN TO START LETTING DOWN UNLESS THERE IS NO QUESTION ABOUT RWY IDENT, BUT I GUESS FATIGUE SET IN AND I LET MY GUARD DOWN.
