Just past the eastern terminus of the Tioga Pass, the entryway to Yosemite National Park, is the quietly beautiful Mono Lake. The area is unique due to its salinity and eerie tufa rock formations that jut out from the water, which give it a completely unreal appearance. Flickr user Pacheco took this amazing photo of the moonrise after a two-day mission to get the perfect Mono lake photo. He absolutely succeeded.

The surrounding area is fantastic as well because it has these little roads that stretch on into the mountains that are perfect to drive on and are often empty of anyone else. California is not often associated with its mountainous landscapes, but in large part thanks to it huge size, it has some of the best natural beauty in the United States.

To International travelers, the name Travelex should sound familiar. They are the largest airport currency exchange operator in the world. But a recent currency exchange study comparing the cost of using Travelex, some of the largest U.S. banks and credit cards revealed what experts already knew.

CardHub's 2013 Currency Exchange Study compared the cost of the currency exchange services offered by 15 of the largest banks in the U.S. as well as Visa, MasterCard and Travelex. The study proved that using a no foreign fee credit card is the way to go on spending internationally. Banks charge an average of exchange rate of 7.1% and Travelex charges 15.5%.

Worried about using a credit card outside of the U.S.? Don't be. Credit cards also provide fraud protection for just that reason.

"Even if a consumer uses a credit card with foreign fees – the average foreign transaction fee is 2.24%, according to CardHub's latest Credit Card Landscape Report – he'll still save 4.86% on currency conversion relative to the services offered by banks and 13.26% compared to airport currency exchange providers," said CardHub CEO Odysseas Papadimitriou in a HeraldOnline report.

The best banks for currency conversion? The CardHub study indicates Northern Trust and Harris Bank lead the pack as they did in the 2012 and 2011 editions of the study while U.S. Bank and SunTrust hold the bottom two spots. On average though, banks are better than Travelex, saving an average 8.4%.

Archaeologists excavating at Lincoln Castle have discovered the remains of an early Christian community, according to a Lincolnshire County Council press release.

The team, which was digging inside the castle to clear the way for an elevator shaft, found the remains of a church that dates back at least 1,000 years. Inside a sealed niche in the wall they found human bones. They had been wrapped in finely woven cloth and while the cloth has long since disappeared, it left its impression on the surrounding mortar. Excavators theorize that these may be the remains of a holy person, as it was common to put relics in church walls and altars in order to make them holy.

An even older find included several skeletons and a stone sarcophagus. The archaeological team is planning to put an endoscopic camera into the coffin to see what's inside without disturbing it.

Seven months after Hurricane Sandy ravaged New York City-area beaches, construction will begin on replacement pavilions for those that were destroyed in the storm. Here's a peek at what destinations like Rockaway Beach and Coney Island will look like, courtesy of Garrison Architects, the firm that was asked to create these modular pavilions.

Structures include bathrooms for the public, stands for lifeguards and offices for beach staff, all of which sit on concrete stilts in order to meet standards put in place by the Federal Emergency Management Agency (FEMA). According to architecture blog Architizer, the materials used to produce the pavilions, like galvanized steel frames, will ensure the structures resist severe weather in the future. The pavilions also have double-ventilated roofs with solar panels on top to save on energy consumption.

According to the architects, the pavilions will be built in Pennsylvania and then transferred via flatbed trucks to New York, where cranes will set them on pile foundations. Ramps and stairs will connect the structures to each other and provide access to the beaches and boardwalks. The new facilities should be put in place just in time for summer.

If your frequent flier miles are languishing unused in your account because you keep coming up against blackout dates whenever you try to use them, then perhaps it's time to switch airlines, or maybe even rethink your booking tactics.

A survey by IdeaWorksCompany looked at 25 of the biggest frequent flier programs to figure out which carriers were best when it came to redeeming frequent flier points. The study checked each of the airline's primary routes to see what level of availability there was for travelers looking to book a flight using their miles.

In what would otherwise make for a great comedy sketch, an Air India captain took a bathroom break during a flight Tuesday night and returned to find a jammed cockpit door. But according to a report by USA Today, this was no laughing matter: after all efforts failed to open the door - even from the inside - the co-pilot landed the plane at the nearest airport, where ground maintenance staff fixed the problem. The plane then resumed its flight, which was making its way from New Delhi to Bangalore.

This is the second strange cockpit incident that's happened with Air India recently; earlier this month, pilots allowed flight attendants to sit in their chairs while they napped, and one of the attendants accidently disengaged the plane's autopilot function. In both instances, no passengers were injured.

Does the mere thought of street food set your stomach to rumbling? If so, you'll want to get yourself to Singapore– the world's unofficial street food (or, technically, hawker centre)– capital. The city is hosting the World Streetfood Congress May 31-June 9. Don't let the stern-sounding name fool you: this 10-day event is all about hedonism, snackie-style.

In addition to a World Streetfood Jamboree featuring the "best street food masters" from all over the world, there are also demos, a first-of-its-kind awards ceremony, discussions on "street food opportunities," live music, and more.

For those in the F & B industry, a two-day conference, The World Street Food Dialogues, will be held June 3-4. It will feature noted speakers/street food experts such as Anthony Bourdain, Saveur magazine editor-in-chief James Oseland, Brett Burmeister, managing editor and co-owner of Food Carts Portland, and Singapore's beloved KF Seetoh, chef, food writer, and founder of the Makansutra food centre and "foodbooks." Makansutra is also the organizer of the World Streetfood Congress.

The pretty young woman in a miniskirt on my TV screen had an interesting sales pitch that caught my attention.

"Access your in-room adult movie selections," she purred. "Where there's no spyware, no malware and no viruses!"

Here, on my television screen at an inn in Oregon, was proof positive that purveyors of in-room hotel porn are getting desperate. Given the choice between accessing porn for free on their computers or paying through the nose for it on pay-per-view, most randy hotel patrons are voting with their pocketbooks.

Indeed, LodgeNet, one of the companies that provides in-room entertainment options to a variety of major hotel chains, filed for Chapter 11 bankruptcy protection earlier this year; and, according to The New York Times, some of their competitors are also struggling. Meanwhile, some hotel chains, like Omni and Marriott, have gotten rid of in-room porn altogether.

The National Geographic Emerging Explorers Program was created to recognize young adventurers, scientists and researchers who have shown particular promise in their chosen field. Each year, Nat Geo selects a group of outstanding men and women who have not only made a significant impact early in their career but whose work shows potential for major breakthroughs down the line as well.

Earlier this week, the Class of 2013 Emerging Explorers was revealed for the first time. This year there are 17 recipients of this honor, each with their own diverse interests and areas of expertise. For instance, conservation biologist Steve Boyes is recognized for his work in protecting Botswana's famous Okavango Delta ecosystem. He's joined by Sayed Gul Kalash, an archaeologist who is striving to preserve the endangered Kalash culture and language in remote Pakistan. Erin Pettit earned her Emerging Explorer honors by studying glaciers to better understand the effects of climate change, while Shah Selbe is an engineer who built a system to track illegal fishing activities across the globe.

This year's class of Emerging Explorers also represents how we are redefining who we perceive as an "explorer" in the 21st century. In addition to the traditional biologists, anthropologists and geologists that fit that mold, we also have Chad Jenkins who is a computer scientists and roboticist working in the field of artificial intelligence. Entrepreneur Tan Le is recognized for her efforts in studying how the brain works and sharing that knowledge on a global scale, while Jer Throp is breaking new ground in the arena of data visualization and digital art. These are new areas of research and study that would have been unheard of even a decade ago.

Each of the Emerging Explorers is awarded $10,000 to assist with their ongoing research. To view the entire Class of 2013, click here.

Last year's Superstorm Sandy devastated much of the East Coast, especially around the mid-Atlantic coastline. New York and New Jersey beaches were hit hard, with scores of houses and even towns wiped out. Many places are rebounding, such as Coney Island, which opened officially for the season in April. Today's Photo of the Day was taken this weekend in New Jersey by Flickr user David Elwood, who also took a shot of Coney Island's Cyclone that we featured last summer. The roller coaster remains are a sad reminder that not everything is back to normal six months later. Many other beach towns have rebuilt and will be open for business this summer, so don't count New Jersey out of your travel plans, they need visitors now more than ever.

Add your travel photos (Creative Commons, please!) to the Gadling Flickr pool to be featured as a Photo of the Day.

UPDATE: Several commenters have noted that the roller coaster was removed this week as part of the ongoing clean-up of the Jersey shore. A photograph captures a moment in time, and while this scene may not exist anymore, it's still a powerful document of history.
